Are there cases where people have to replace multiple teeth with implants?

Hi, From the photo, you may have a benign skin condition called “lichen spinulosus”. The cause is not known and it is not contagious. The condition is harmless. Moisturizers and topical retinoids may help improve the appearance. Do see a doctor if the condition really bothers you and if you wish for some prescription creams to help improve it.

Dentists choose treatment plans based on many different factors. Some of these factors have nothing to do with clinical data. As a patient, your dentist should go through the different treatment options with you so that you understand the treatment itself, and the long term maintenance required with that selection. Keeping the tooth by performing root canal treatment and a crown may mean that the tooth may still crack further and require extraction at a later date.
