Athletic mouthguard I designed for the Naval Academy.

Custom dentist made pressure laminated mouthguards provide the most comfortable fit and the best protection against injury. They are more durable and longer lasting than over the counter mouthguards. I can make the mouthguards in your team colors and with the team logo.

Mouthguards protect your teeth, mouth, face, lips and jaws. Research has shown that custom made mouthguards reduce the incidence of concussions and brain injuries. I have attached below an article from The Academy of General Dentistry Magazine, August 2014, on mouthguards reducing brain injuries.

Dr. Gentry explains CAD/CAM technology and 3D printing in dentistry.

CAD/CAM is an acronym for computer-aided design/computer-aided manufacturing. CAD/CAM technology has been increasingly incorporated into dentistry over the past 20 years. CAD/CAM technology is used by dentists and dental laboratories to provide our patients with 3-D milled ceramic crowns and other types of restorations, and to fabricate abutments for dental implants, used to replace missing teeth. A digital impression is taken of the patient’s teeth or dental impression, and the restoration is milled from a single block of tooth colored ceramic material in a milling chamber.

For home teeth whitening, Dr. Gentry recommends Opalescence Go.

Professional results—to go

Opalescence Go is the professional alternative to over-the-counter whitening options that Dr. Gentry recommends, and has for sale in his office for only $50 per kit. It’s a simple, fast, and great-tasting way to start a whitening treatment, or for whitening touch-ups. With no impressions or custom trays necessary, Opalescence Go is ready to use right out of the package!

  • Opalescence tooth whitening gel contains PF (potassium nitrate and fluoride). Potassium nitrate has been shown to help reduce sensitivity. Fluoride has been shown to help reduce cavities and strengthen enamel. Together they help to improve the overall health of the teeth.
  • No impressions, no models, no lab time
  • Sleek and comfortable; adapts to any smile
  • Discreet, clear tray material
  • 10% – wear 30-60 minutes

Invisalign

invisalign5

Invisalign® straightens your teeth without wires and brackets, using a series of clear, customized, removable appliances called aligners. It’s virtually undetectable, which means hardly anyone will know that you’re straightening your teeth.

CLEARLY DIFFERENT

The Invisalign System combines advanced 3-D computer graphics technology with 100-year-old science of orthodontics. Invisalign aligners are designed to move your teeth in small steps to the desired final position. Each aligner is precisely calibrated and manufactured to fit your mouth at each stage of the treatment plan. Your first step is to visit our office and see Dr. Jeanette Coutin-Gentry to determine if Invisalign is right for you. Dr. Coutin is an Invisalign Certified Preferred Provider with many years of experience with Invisalign.

After sending precise treatment instructions, Invisalign uses advanced computer Invisalign technology to translate these instructions in a sequence of finely calibrated aligners — as few as 12 or as many as 48. Each aligner is worn for about two weeks and only taken out to eat, brush and floss. As you replace each aligner with the next, your teeth will begin to move gradually — week-by-week until the final alignment prescribed is attained. Then you’ll be smiling like you never have before!

While the results may appear the same—a confident, beautiful smile—when you stop and actually compare Invisalign® to other teeth-straightening options, the advantages become quite apparent. Knowing the pros and cons of each option ahead of time will help you make a more confident decision.

Cracked teeth/tooth fractures.

unnamed-2
Cracks on back molars.

If when you bite down, you feel a sharp pain you may have a cracked tooth. A tooth crack may have been caused by:

  • Chewing on a hard object or food such as ice, nuts, candy, or popcorn.
  • An accident, like a blow to the mouth.
  • Grinding or clenching your teeth.
  • Weak tooth caused by wear or large old fillings, or root canal.

If you feel pain when you bite down on a tooth please let Dr. Gentry know and he will evaluate the tooth and discuss the best treatment protocol for you. If treated early, the cracked tooth possibly can be treated with a bonded filling or a crown. If the crack is deeper the tooth may require a root canal or even extraction.
