Abour Crowns and Bridges
A crown is a dental restoration that involves entirely covering a tooth with an extremely protective material that is resistant to fractures, extreme temperatures and acidic foods.
Everyday activities such as chewing can put stress on our teeth, and over time this may manifest as visible signs of wear and tear. Although almost unnoticeable to the untrained eye, your dentist may notice faint fracture lines through your teeth, as well as generalised erosion of the surfaces. These are an artificial weak point in the tooth, and if you chew or bite together just a bit too hard, you can accidentally break off part of the tooth. To avoid this unnecessary trauma, your dentist may recommend a crown for the tooth. This will enhance its strength.
