Tooth sensitivity is an all too common problem among dental patients. If eating certain foods or simply touching a tooth causes you pain, you should know why this may be happening and what can be done about it.
Tooth sensitivity occurs in most cases because the portion of the tooth known as the dentin has been exposed. The dentin contains nerve fibers that inform and alert the brain about the current environment of the tooth (temperature or pressure changes). The enamel protects the tooth from environmental extremes.
Receding gums are the most common cause for dentin exposure — the enamel only protects the crown of the tooth and is not present on the root of the tooth. Acids in certain foods can then begin to erode the dentin around the roots and expose nerves. Sweet items (mainly sugar) and temperature shifts irritate the nerve endings, causing pain.
While receding gums (most commonly caused by brushing too hard and too often) may be the most common cause for sensitivity, it isn't the only one — tooth decay may also lead to it. Untreated, decay works its way into the tooth pulp and irritates the nerves. Treating the decay and filling the tooth may also cause sensitivity unless the dentist places a lining designed to minimize it temporarily while the area heals.
Alleviating pain from sensitivity begins with how you brush your teeth. Remember: the goal of brushing is to remove plaque, which does not require vigorous action. Brush gently with a soft-bristled brush and not too often. We might even recommend not brushing a very sensitive tooth for a few days to give the tooth a rest. You should also brush with a toothpaste containing fluoride, which will help strengthen the tooth surface against the effects of acids and sweets.
During an office visit, we can also apply a fluoride varnish or use certain filling materials that will serve as a barrier for the sensitive area. For cases where decay has irreversibly damaged the tooth pulp, a root canal may be the best treatment.
Tooth sensitivity isn't necessarily something you have to live with. There are treatments that can relieve or lessen the pain.

Fans of the classic bumbling-buddies comic film “Dumb and Dumber” will surely remember the chipped front tooth that Jim Carrey sported as simpleminded former limo driver Lloyd Christmas. Carrey reportedly came up with the idea for this look when considering ways to make his character appear more “deranged.” He didn't need help from the make-up department, however… He simply had his dentist remove the dental bonding material on his left front tooth to reveal the chip he sustained in grade school!
Creating a Bond
A dental cosmetic bonding involves application of a composite filling material that our office can color and shape to match the original tooth. Bonding material can be used to replace the lost portion of tooth or to seamlessly reattach the lost portion if it has been preserved and is otherwise undamaged. Little to no removal of existing tooth surface is needed. This is the quickest and lowest-cost option to repair a chip.
When a relatively large portion of the tooth is missing, a crown is often the better choice. It fully encases the visible portion of the remaining tooth above the gum line and is shaped and sized to match the original. It can be made of tooth-colored porcelain fused to metal crowns or all-ceramic (optimal for highly visible areas). A small amount of the existing tooth surface will be removed to allow the crown to fit over it.
A veneer can be used to hide smaller areas of missing tooth. This is a thin, custom-made shell placed on the front of the tooth to give it a new “face.” Some removal of existing tooth surface also may be necessary to fit a veneer.
A chipped tooth makes an impression, but generally not a flattering one. Nearly 20 years after “Dumb and Dumber” hit the theaters, the only thing Jim Carrey had to do recently to hint at a sequel for his nitwitted character was tweet a photo of that goofy grin!
