Jagged teeth can be caused by a variety of factors, including trauma, tooth decay, or grinding. Jagged teeth can be painful and can make it difficult to eat, speak, and smile. In some cases, jagged teeth can also lead to infection.
Dentists can file jagged teeth to smooth out the rough edges and improve the appearance of the tooth. Filing jagged teeth can also help to prevent pain and infection. In some cases, filing jagged teeth may also be necessary to prepare the tooth for a filling or crown.
