Chipping a tooth is something that can occur a number of different ways; from getting hit in the mouth to something as simple as chewing on hard foods. Chipped teeth should always be evaluated by a dentist to ensure that the damage is assessed correctly. Depending on the size and location of the chip, there are a number of solutions available.
For small cracks and chips that only affect the enamel of the tooth (the outer white surface) your dentist can choose to lightly polish the area to smooth out the rough edges, or they can apply a bit of filling material. Small chips are often not very serious and repairs are mainly performed for aesthetic purposes as well as to protect the tongue, lips and gums from the sharp edges of the chipped tooth.
For more serious chips where the nerve of a tooth becomes exposed your dentist will have to assess and decide whether a root canal or a crown is required. A telltale sign that a nerve ending of a tooth is exposed is when there is acute pain on the tooth when it is exposed to hot or cold temperatures.
Another option for repairing chipped and crack teeth is to have veneers placed. After your dentist addresses any issues with the health of the tooth resulting from the cracks or chips (such as exposed roots or nerve endings), veneers can be placed over top to improve the overall look of your smile.
