The Truth about Baking Soda & Teeth Whitening…

February 12, 2019

Patients ask us about various topics all the time. As their doctor, and an
expert, we really want to feel comfortable answering those questions
with accurate information. I’ve received several questions from dentists
about the use of baking soda (sodium bicarbonate) as an alternative to
commercial toothpaste, and especially regarding its claimed ability to
whiten teeth.  Obviously, these dentists have been asked these same
questions by their patients, who’ve seen wild claims all across the
internet. As a consequence, I took a look at the claims on the Internet
about baking soda. To say I was blown away with the inaccuracy
(including some articles written by dentists) is an understatement. So
I thought the following information may be of help to you. Search the
Internet regarding brushing your teeth or whitening your teeth with
baking soda, and among other ridiculous things, you’ll routinely see
the claim that baking soda is VERY abrasive to use on your teeth –
so if you use it, don’t use it every day. Absolutely wrong! These
statements are not only wrong, but they’re pretty much as wrong as
you can get. Baking soda (the stuff in the box in the super market) is,
by far, the lowest abrasiveness of anything you would ever brush your
teeth with. Here’s the problem – non-scientists writing articles based
on assumption, and not proven fact. And once ONE person writes
something, others quote him or her. Then when you have several
people saying that same [false] thing, people state it and believe
it as fact. After all, if enough people say the same thing, it must be
fact, right? Wrong! And the most disconcerting thing for me is that
some of these articles have been written by dentists, who also simply
read what others said on the internet, so they too assumed that
baking soda is excessively abrasive. Why do so many people
“assume” baking soda is extremely abrasive? It’s because the
particles are large and have sharp edges, so it “feels” gritty when
you touch it. Below on the left you see a microscopic photo of
baking soda particles. Notice how they have edges and corners.
Below on the right you see silica particles, which would be the
most common abrasive in toothpastes. Notice how rounded and
smooth the silica particles are. But also realize that the baking
soda particles are much, much larger than the silica particles.
Baking soda particles can be as much as 15 times larger than silica
particles in toothpaste.
So what’s the difference? Silica particles are much, much harder than
baking soda particles. When you forcefully rub two hard objects
against each other, the harder object will have almost zero damage,
and the softer object will be greatly scratched and damaged.
For example, a diamond is a hardness of 10 on the Mohs Hardness
Scale, and glass is rated at 5. So diamond is two times harder than
glass. Well, that’s not exactly true because the Mohs Hardness
Scale is an ordinal scale, so there is no data on how much difference
there is between the numbers. But you already know if a diamond is
firmly rubbed against glass, it will scratch the glass, but the diamond
will not be damaged. Mohs Hardness of materials (remember this is
an ordinal scale, so there is no mathematical formula of consistent distance between each number):Tooth enamel = 5Tooth dentin/root = 3Baking
soda = 2.5Hydrated silica in toothpaste = 5-7Baking soda “feels” much
more gritty than regular toothpaste (which usually has hydrated silica
as the abrasive) because the particles are larger, and the edges are
rough. Whereas silica particles are more round, smooth, and many
times smaller. So baking soda “feels” more abrasive – but it’s not. 
The fact is that Baking Soda, being much softer than tooth enamel,
and very slightly softer than even tooth dentin, will not create much
damage (abrasion) to the tooth. The American Dental Association has
published their RDA (Relative Dentin Abrasivity) to measure the
abrasiveness of various toothpastes. The RDA abrasiveness categories
are:Low 4-70 (plain water is 4. Baking soda is 7.)Medium 70-100High
100-150Harmful 150-250 The FDA limits abrasiveness to a maximum
of RDA 200. Get this…the RDA of Arm & Hammer baking soda is only 7.
Whereas the most typical tooth paste will be in the 70-100 range with
many far above that. THAT is how gentle baking soda is, as far as
abrasion to your teeth. Of course, keep in mind that commercial
toothpastes that claim to be baking soda toothpastes also contain other
abrasives. So using baking soda in the commercial toothpaste may
be thought of as somewhat of a marketing gimmick to get you to buy
the toothpaste. This means you can brush your teeth with more paste
and for a longer time if you’re using straight baking soda mixed to a
paste with only water. That alone will help physically remove more
bacteria and more stain. Why? Stain will typically be softer than baking
soda, so, though baking soda will not cause much abrasion of your teeth,
it’s still hard enough to scrape off many types of stain from your teeth. 
The main problem with using straight baking soda/water paste? No
fluoride. And of course, baking soda is harder than gingival tissue, so
brushing longer may cause gingival abrasion and recession over time.
So there’s good and bad here.
Baking Soda to Whiten Your Teeth
So now let’s talk about the ridiculous claim that brushing with baking
soda will whiten your teeth. This is simply wrong…period! There has
never been any scientific study that even hints that baking soda may
whiten your teeth.
 
Of course, if you’re talking about using baking soda to simply brush
with to remove stain from the surface of your teeth, then yes, baking
soda will do that, just like any other toothpaste in the world. But does
it have any other chemical or other means of any kind that will “whiten” your teeth? Absolutely, positively not!
But now….the REALLY DANGEROUS information.
Of course, all dentists know how acid ravages tooth structure. When you do an Internet search of whitening your teeth with baking soda, often
you’ll find instructions to add lemon juice, apple cider vinegar or some
other acidic ingredient along with the baking soda. And you already
know what a bad idea THAT is! 
But wait…it gets even worse…
You’re mixing baking soda, which is at least somewhat abrasive, and acid together. Gee, doesn’t that remind you of microabrasion products that
we dentists use on teeth to remove the surface of tooth structure – such as removing surface dark or white spots? Possibly the most popular
microabrasion product out there is Ultradent’s Opalustre. It’s an excellent product. It has hydrochloric acid mixed with silicon carbide
microparticles. The acid SOFTENS the surface tooth structure, which
the abrasive particles quickly remove. Mixing baking soda and lemon
juice or apple cider vinegar will do exactly the same thing, but on a
less aggressive scale. When thinking about patients doing this
continually over time, this is the perfect way to wear away their tooth
structure. And the thing that really kills me is that most using this
technique falsely believe it’s a very safe and “natural” way to whiten
teeth. Yeah, sure! “Natural” like a rattlesnake bite! But it’s one of the
worst, most ineffective, and especially permanently damaging things
you can do to your teeth.

Experience Does Matter With Dentistry at MOD Squad Dental

July 12, 2017

Example 1 of an implant placement to replace this front tooth #8 with Dr. Greg Friedman

Example 2 of a new patient we saw this week in the office with several implants including front teeth, #8, & #9

Often patients call our practice asking, “How much do you charge for dental implants”?  We, for the very reason illustrated in the two radiographs above do not quote fees over the phone.  My best advice to patients seeking a dental professional for minor or extensive dentistry is to do your research.

Do not just make your decision strictly from a quoted cost you received over the phone.  Experience does matter when it comes to dentistry.  From the materials used to the education of the dentist.  Just because a dentist claims to be a specialist for a particular procedure does not mean they are.  As proven in the above second radiograph completed by a “dental implant specialist”.  Use your online resources wisely.  Sites such as Yelp & Google are great tools to research a dentist and his/her practice.  But buyer beware!  “Just the other day I saw a “dental implant specialist” that had two Yelp accounts.  One with 2.5 stars and right next to it a new Yelp account under a different name with 5 stars for the same “dental implant specialist”, stated Dr. Friedman.  Both accounts do show next to each other when searching this particular practice.  This for example is something to be aware of and notice.

Our patient above has not or will not ever need a removable “flipper” or appliance at all during his implant process unlike other practices.  This puts our patients at ease and comfortable while going through the implant process.  At Mod Squad Dental, not only are our doctors looking for the implant placement to be functional but also aesthetically pleasing as if it were a real tooth.

If you have questions about replacing missing teeth or dental implants, call Mod Squad today for your complimentary consultation…

Because experience does matter!!!

Smile Pretty with Porcelain Veneers from MOD Squad Dental

March 12, 2015

159289454Smile! You’re on candid camera! Ok, well not really, but if you were, would you smile for the camera or would you try to hide your smile? If you’re one of those smile hiders, then it’s time to do something about that so you can smile with confidence. Porcelain veneers conceal the smile you don’t want to show and reveal a new smile that you wouldn’t think of hiding. Dr. Greg Friedman and his team at MOD Squad Dental have created beautiful smiles for many people in and around San Diego, CA, and they can do the same for you.

What are Porcelain Veneers?

Porcelain veneers, also called dental veneers, are made of micro-thin layers of dental porcelain or ceramic that are bonded to the facial surface of the teeth in your smile zone. As such, they cover a number of cosmetic smile flaws including teeth that are chipped or slightly cracked; stained or discolored teeth that have not responded to teeth whitening; somewhat crooked teeth; and teeth that have gaps in between them. In addition to covering damaged teeth, veneers also help protect those teeth from further damage.

Porcelain Veneers in San Diego, CA

Once you and Dr. Friedman determine that porcelain veneers are the best cosmetic dentistry option for you, you are on your way to a beautiful new smile. It usually only takes two visits to complete the process of having your veneers placed. At the first appointment, Dr. Friedman will take an impression of your teeth that our dental lab will use to fabricate veneers that are a perfect fit and match for you. Then, he will prep the teeth by removing a minimal amount of enamel, so your veneers will lay flush with the rest of your teeth. After this appointment, you’ll wear temporaries until your permanent veneers are ready. Then, you’ll return to MOD Squad Dental in a few weeks to have your permanent veneers bonded in to place. With your new smile, you’ll be looking for the camera!

Shhhh… with Invisalign®, only you and Dr. Friedman will know you have Braces

January 28, 2015

invisalignIf you’re conscious of your smile because of crooked teeth, but as an adult you don’t want to endure the hassle or the appearance of traditional braces, then Invisalign clear plastic aligners may be the solution for you. As the name implies, Invisalign straightens your teeth almost invisibly. Dr. Greg Friedman at Mod Squad Dental in San Diego, CA, is an Invisalign Certified Provider who won’t tell anyone you have braces!

Invisalign Aligners Made Just for You

The first step of your journey to a smile with straight teeth is meeting with Dr. Friedman to decide if Invisalign is right for your unique circumstances. If the answer is yes, then we’ll take x-rays, photos and impressions of your teeth that Invisalign will use to create a 3D image of your mouth. With this, Dr. Friedman will map out a treatment plan that shows how your teeth will gradually move through the process and what your smile will look like upon completion.

This treatment plan is also what the Invisalign lab uses to fabricate your custom-designed aligners, which you’ll wear every day for most of the day. Made of smooth, BPA-free plastic, your aligners are smooth, so they won’t bother your gums and checks the way metal braces can.

Your aligners come in a series of sets for your upper and lower arches. You’ll wear each set for approximately two weeks and then move on to the next set. As you progress through the sets, you’ll see your teeth gradually move into position. Although everyone’s circumstance is different, in most cases the process is completed in about one year. Then, you’ll have the straight teeth you’ve always wanted and you won’t want to keep that a secret!

To Quickly Repair Your Smile, Choose Cosmetic Bonding with Dr. Greg Friedman

January 14, 2015

Shutterstock Lumineers Close UpIs there a little something you’d like to fix about your smile? If the answer is yes, then you should consider cosmetic bonding. Dr. Greg Friedman at Mod Squad Dental in San Diego, CA, practices the artistry of cosmetic bonding to restore smiles throughout southern California.

With cosmetic bonding, Dr. Friedman can repair a number of smile imperfections including:

  • Stained or discolored teeth that do not respond to teeth whitening
  • Chipped teeth
  • Cracked teeth
  • Teeth that are slightly misaligned
  • Teeth that have a gap in between them
  • Worn teeth that make your smile look uneven

What is Cosmetic Bonding?

Cosmetic bonding uses composite resin materials to restore and rebuild damaged or imperfect teeth. With these composite materials, Dr. Friedman can blend colors in order to perfectly match the color of your other teeth. In some case, he may recommend teeth whitening before the bonding process in order to ensure your best smile, and because composite materials are not responsive to teeth whitening gels.

Once you and Dr. Friedman determine that cosmetic bonding is the best option for repairing your smile, you’ll probably only need one appointment for the entire process. First, the dentist will prep for cosmetic bonding by applying a gentle phosphoric acid solution to the surface of the teeth in order to help the bonding material adhere better. Then, he will apply the composite resin layer by layer, shaping, sculpting and hardening each layer with a curing light as it is applied. This process is repeated until the desired appearance is achieved. Finally, the teeth are polished to a natural-looking sheen.

Cosmetic bonding can last for years with proper care. Brush and floss your teeth twice every day as you usually do, and be careful not to bite down on hard objects with teeth that have cosmetic bonding.

Call Our Office Today

If you would like to schedule an appointment for cosmetic bonding, call the office of Mod Squad Dental in San Diego, CA. Dr. Friedman and his staff also serve patients in Scripps Ranch, Poway and Rancho Pensaquitas.

MOD Squad Dental Delivers Unbelievable Results with Professional Teeth Whitening in San Diego, CA

December 23, 2014

524227687Are you struggling to correct stained or yellowed teeth? Tooth discoloration and staining can cause you to hide an otherwise healthy smile. Discoloration can be caused by many different factors including: drinking coffee, tea, soda, and red wine, or smoking. The aging process also naturally stains and darkens our teeth. But you don’t have to tolerate a diminished smile. You can make an appointment with Dr. Friedman today for a high quality professional teeth whitening treatment. MOD Squad Dental is a trusted San Diego cosmetic dentistry. Dr. Friedman proudly restores smiles daily throughout the Scripps Ranch and surrounding San Diego, CA communities.

Why Choose Professional Teeth Whitening?

Professional teeth whitening is the only reliable tooth whitening method. Other options just don’t yield consistent results. Teeth whitening toothpastes are guilty of this. They can’t change the color of your enamel; they can only polish away shallow surface stains. Other over-the-counter teeth whitening products including, whitening rinses, strips, trays, and gels are also highly unreliable. Though they contain the bleaching agents necessary to change the color of enamel, they are heavily diluted. Because of this, it can take several weeks of daily use before any significant results are noticed. That’s why Dr. Friedman offers a professional teeth whitening solution with the Kör and Zoom teeth whitening systems.

What Is Kör Teeth Whitening?

The Kör teeth whitening and deep bleaching system works through the absorption of oxygen into your tooth surfaces. The oxygen from the Kör whitening gel is absorbed deeply into the tooth, dissolving stains and discoloration molecules. Unlike most other teeth whitening treatments, Kör is entirely permanent. Kör teeth whitening offers:

  • Natural looking results
  • Effective on darkened teeth
  • Effective on sensitive teeth and gums
  • Comfortable and easy to complete
  • No dietary restrictions post- treatment
  • No need for touch ups
  • Effective for ages 14 and up

What Is Zoom Teeth Whitening?

Zoom teeth whitening is a professional bleaching system that effectively lightens discoloration of enamel and dentin. Zoom works through a hydrogen peroxide mixture that is broken down, allowing oxygen to enter the enamel and dentin to bleach away staining, but leave natural tooth structure unchanged. Zoom teeth whitening takes less than an hour. Zoom hydrogen peroxide whitening gel, works with the Zoom light to quickly penetrate teeth and break up the stains and discoloration. Immediately after treatment, a sensitivity-reducing fluoride paste-gel is applied to your teeth to reduce any discomfort.
