Hello Dr Hughes. I am 65 years old and have noticed that over the past few years, that the upper right teeth appear to be moving forward. I can see that now one front tooth appears to be beginning slightly to overlap in the middle. I do not want the tooth to move any further. At my age, I do not want to wear a permanent brace. My dentist thinks that a brace worn just at night may halt the teeth overlapping further. Would you kindly give me advice on this? Many thanks for your help.
