Fact vs. fad: activated charcoal

102311430_sIt seems like common sense that putting something messy and black on your teeth would only serve to make them the opposite of white. So what gives with all the recent chatter about activated charcoal and whiter teeth?

According to the Journal of the American Dental Association, “There is no evidence that shows dental products with charcoal are safe or effective for your teeth.” Dr. Kimberly explains it this way, “Bleaching your teeth is all about changing the inherent color of the teeth. If you’re using a product that’s rough on the enamel –– like activated charcoal –– you can wear the enamel away causing your teeth to be actually more porous, sensitive, and look more yellow. And once the enamel is damaged, it’s permanent.”

So in short, stick with an ADA-approved bleaching system from your dentist’s office … and save the charcoal for the barbecue.

Toothbrush Tips

Ever wonder about the best way to care for your toothbrush? It’s pretty simple, really, and you’ll be in good shape if you follow these basic steps: 

41140056 - tooth brush in glass isolated on white background1) No sharing. Don’t get us started on the enormous bacterial exchange that happens when you share a toothbrush. Just say no. 

2) Rinse thoroughly. After brushing, rinse your toothbrush well.

3) Store upright. Store the toothbrush in an upright position to allow it to dry thoroughly. Separate it from other toothbrushes to avoid cross-contamination.

4) Avoid closed containers. Don’t store toothbrushes in closed containers that will promote bacterial growth; a toothbrush needs the open air. 

5) Replace every 3 months. Toothbrushes wear out, bristles become frayed with use, and their ability to clean effectively diminishes. The best rule is to replace a toothbrush every 3-4 months. 

White, Whiter, Whitest


Whitening toothpaste, whitening strips, whitening gels. The dizzying array of choices in the toothpaste aisle is intimidating, to say the least. So which to choose, what is best?

The quick answer is this: the products at your local drugstore all have similar whitening ingredients to what’s available at your dentist’s office, the main one being peroxide. The difference between what you can buy at the store and what your dentist provides is a matter of concentration. The drug store products all have a very low percentage of active ingredient, between 1 – 2%, versus up to 35% in the products available from your dentist’s office. Professional teeth whitening at the dentist’s office is a more concentrated peroxide product, and therefore more effective. 

So which is better? Dr. Kimberly recommends using 35% Opalescence bleaching gel in custom trays, made by your dentist and worn at home for 30 minutes a day until the desired shade is achieved. On average, it takes 10-14 days and the results are the best out there.

And to stay white, skip stain-causing foods such as coffee, tea, and red wine –– and avoid fad teeth rinses like lemon juice, apple cider vinegar, and activated charcoal because they will damage and erode the enamel of your teeth. Whatever product you purchase, make sure it has the ADA seal, which means it’s safe and effective. For questions regarding teeth whitening, please call our office at 949 640 0300.

Preventing Sports Related Dental Injuries

Waterpolo - Athens Olympic Games 2004 - Men's Final - Hungary v Serbia and Montenegro

Did you know that one third of dental injuries are sports related? It’s true. So how can you protect your teeth and mouth in contact sports? The answer is a custom fit sportsguard/mouthguard, which can help you to avoid injury and in turn, dental visits. Sportsguards not only protect your teeth, but your tongue, lips, face and jaw too. A 2014 study in an issue of General Dentistry showed that a custom-made, properly fitted, pressure-laminated mouthguard may also reduce the incidence of sports-related concussions.

Mouthguards are used in sports including football, basketball, lacrosse, water polo, and ice hockey among others. For more information on custom-fit sportsguards please call our office at 949 640 0300. 

Dr. Kimberly’s Top Five

Processed with VSCO with f1 preset

When it comes to teeth, ever wonder what your dentist’s favorites are? Check out the whats and the whys of Dr. K’s top five below.

1) Sonicare toothbrush: Why? It’s a superior clean, removing plaque and keeping both teeth and gums healthy. No regular toothbrush can compete. She brushes with it twice daily for 2 minutes each time (and after lunch with a regular toothbrush). 

2) Listerine Soft Mint: Why? It reduces plaque, bacteria, and keeps your breath fresh. She rinses with it twice a day. 

3) Opalescence toothpaste: Why? It’s an anti-cavity, surface stain removing toothpaste that tastes as good as it works. She uses it daily.  

4) Opalescence teeth whitening gel: Why? Because it’s the best teeth whitener around. She uses it to touch up whitening after a cleaning.

5) Cocofloss: Why? It’s softer and easier to manage than regular floss and the flavors are fairly delicious. She uses it daily. 

Stealth Stainers

NCI5N8UL3Z (1)

If someone asked you to name the worst teeth-staining foods and drinks out there you’d probably say coffee, tea, and red wine. And you’d be right. But there are other stealth stainers that might surprise you. Like what?

- LEMONADE: due to its high acidity, lemonade erodes enamel and leaves teeth vulnerable to staining. 

- BERRIES: both blue and black, berries may scream summer but they also scream stains. 

- WHITE WINE: yes, white wine –– it’s acidic and opens your teeth up to staining by other foods. 

- POPSICLES: brightly colored and sugar filled, popsicles are a double dose of bad for your teeth.

- POOLS: who knew? The chemicals used in pools can give your teeth a brown hue. 

- BALSAMIC VINEGAR: its dark color and high acidity make it one of the worst offenders. 

- MARINARA SAUCE: acidic and tomato red, this sauce clings to both pasta and your teeth.

- COLA: brown, fizzy, acidic and pure sugar –– need we say more? 

So what can you do? Indulge in your favorites, but aim for moderation. And make sure to rinse your mouth with water (to remove the acidity) before you brush your teeth.
