Nice note I received from this wonderful patient :-)))

I consider myself very lucky to have found such an outstanding dental professional.
Over the years he has done some truly amazing work for both my husband and me. He filled, he fixed, he patched, repaired and replaced, while employing the latest innovations in dentistry.  All this with a cheerful, kind attitude that would put the most anxious person at ease. Not just best in his field, but BEST ALL AROUND! You can not imagine just how wonderful my new teeth feel! The fit is simply perfect!! My whole outlook has changed and I feel like a new person. Thank you, thank you!  I could not be happier!!!
We have the highest regard for Dr. Philip Gentry and recommend him without reservation.

Cosmetic reconstructive case of the day.

This patient is a 19 year old young man who suffered a seizure and passed out and smashed his face on a concrete sidewalk. He fractured his upper central incisors exposing the nerves. I was able to save the teeth with root canals, buildups, and porcelain crowns. These are the before and after pictures.

Cavity of the day

This patient is a 26 year old woman who uses an Advair asthma inhaler. The inhaler causes dry mouth which allowed these cavities to form. If you use an inhaler always rinse out with water after and brush your teeth as soon as you can following inhaler use. Make sure to see your dentist regularly to check for tooth decay. The cavity in the last molar was to the nerve. I was able to avoid a root canal by placing a vitrebond pulp cap over the exposed nerve and a ceramic composite restoration to restore the tooth. Looks great!!!


Dr. Gentry’s list of 15 foods that stain teeth.

Article published in The University of Maryland Magazinephilfoods

  1. Coffee

Your morning cup of Joe might be a necessity that you cannot live without. However, coffee contains dark pigments and healthy but acidic polyphenols, and tannins that can lead to staining and discoloration. Plus, coffee is also very acidic, and acidic foods lead to tooth decay.

  1. Tea

Tea has stain-causing tannins. If you’re constantly sipping on tea throughout the day, avoid Earl Grey and choose a lighter colored variety such as an herbal or green tea. To fight against tea stains, research published in the International Journal of Dental Hygiene says to add a little milk to your cup! The casein in milk was found to significantly prevent and reduce tea-induced stains.

  1. Red Wine

Those same troublesome tannins exist in your favorite glass of vino, too. Try pairing your glass of Pinot Noir with a handful of almonds to help counteract staining. The act of chewing hard foods like nuts can help scrub away plaque from teeth and mitigate staining. Swish out with water immediately after drinking wine.

  1. Berries

Blueberries, raspberries, and strawberries are very healthy and packed with antioxidants, but due to their darker hues, berries will cause staining of the teeth. Eat berries and brush right after.

  1. Curry

Although the exotic spices taste amazing, those yellow and red yummy spices also tint your teeth, thanks to their deep pigmentation. The best way to prevent staining here is to make curry an “every once in awhile” treat. Your smile will thank you.

  1. Hard Candies

Hard candies like Jolly ranchers might be one of the worst foods for your teeth. They are both sticky and acidic. Choose non-sticky dark chocolate instead.

  1. Tomato Sauce and Ketchup

Anything that can stain your clothes can stain your teeth. Tomatoes are also acidic. Brush after your spaghetti and meatballs.

  1. Cherry and Cranberry Juice

All fruit juice puts your teeth at risk of discoloration, especially when the fruits are richly pigmented like cherries or berries. Not to mention, fruit juice is often stacked high in sugar, which can act as a breeding site for bacteria in your mouth and lead to more dental damage and discoloration.

  1. Soda

Regular and diet soda is very acidic to the body and, as a result, is damaging to your dental health. Drinking plain water is the best choice for your teeth. Drinking through a straw may help a little.

  1. Balsamic Vinegar and Soy Sauce

Salads are healthy for you, but that balsamic may do a number on your teeth. Not only is balsamic dark in color, but it’s rather sticky and will latch onto teeth, which can lead to staining if it’s not brushed away soon after eating. Avoid too much soy sauce, it stains and contains too much sodium anyway.

  1. Beets

Whether you enjoy them in your morning veggie juice or consume them whole, beets can be incredibly staining to the teeth. Brush your teeth after eating beets. You can also try pairing them with foods that are less damaging to your mouth—like cheese! Studies show that cheese can reduce acids in the mouth.

  1. Popsicles

Popsicles may be lower in calories than other dessert options, but due to their sugar content and fruit juice base, and will stain your teeth. Chew sugarless gum instead to increase your saliva production, which helps to neutralize and counteract those acid attacks.

  1. Gatorade

Some research suggests sports drinks are even more harmful to your smile than sodas. Researchers from New York University found that excessive consumption of these types of drinks can weaken and damage the tissue in your teeth because of a combination of acidic components, sugars, and other additives.

  1. Grapes

If wine will turn your smile dark, then you better believe its main ingredient will do the same. Grapes are deeply pigmented fruits and may cause staining when eaten often. Brush after eating grapes.

  1. Lemon

Hot water with lemon in the morning has become a popular with celebrities. But citrus fruits like lemon or lime are highly acidic and can erode the enamel on your teeth—in turn, revealing yellow dentin tissue below. Avoid acids, drink water.

Crowns of the day

Here I made 2 porcelain crowns for this patients’ upper lateral incisors. The crowns filled out his smile nicely and look fantastic. Notice how large his upper central incisors looked before and how natural his upper teeth look after.

Here I made 4 porcelain crowns. His teeth are somewhat yellow, so I made the new crowns slightly lighter than the rest of his teeth to brighten up his smile.




Worn down teeth

This patient had worn down her teeth due to years of grinding. I filled in and restored the tops of the teeth with dental ceramic composite bonding, and made her a nightguard to protect her teeth in the future.
