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!

In a healthy tooth, a coating of enamel protects the crown — the part above the gum line — and a layer of cementum protects the tooth root below the gum line. Enamel and cementum are inert (nonliving) substances that do not respond to stimuli such as heat or cold; however, dentin, the living tissue below them, does. Dentin contains numerous microscopic tubules that readily transmit stimuli toward the nerve-filled center of the tooth (pulp tissue). Loss of protective enamel or cementum leaves dentin exposed to all sorts of stimuli in the oral environment, which can trigger “dentinal hypersensitivity” — anything from a mild twinge to shooting pain.
Fortunately, there are many options for treating hypersensitivity. The key to selecting the most appropriate one(s) is determining the cause(s). Some of the more common reasons for sensitivity due to dentin exposure include:
- Enamel erosion caused by an “acid attack” related to external (extrinsic) causes — i.e., consumption of acidic beverages/food — or internal causes — i.e., regurgitation of stomach acids due to gastroesophageal reflux disease [GERD] or the eating disorder bulimia
- Using an overly abrasive brush or toothpaste, brushing incorrectly or too frequently, or brushing too soon after an “acid attack” — all of which can result in a loss of enamel
- Tooth decay (dental caries or cavities)
- Tooth fracture or chipping: tooth grinding (bruxism) is a common cause
- Worn fillings
- Gum recession, due to age or improper tooth brushing, that exposes the tooth root
- Gum disease, which can result in gum recession
Sensitivity can also occur following a procedure like treating a cavity. Normally it subsides within a couple of weeks or so but if it continues there may be another underlying cause.
Whatever the source(s) of your discomfort, our office can get to the bottom of it and recommend an effective course of treatment that meets your personal needs!
