HI Scarlet, could you tell me how many teeth are missing in your mouth. I have 6 teeth missing now, and my appearance has changed slightly. They are all back teeth, i have all my front teeth and if i smile you cant see that the back ones are missing. I had no choice because most of them were root canaled and 2 of them were really decayed. My dentist says that it could be a problem in later years, that the teeth that are there will get weak because of chewing. These days i tend to eat soft food.
