Q. I am 48 year old with good teeth but upper tooth wear to 3B,4B,6B, through brushing to hard- leaving my teeth worn away in a v shape at the gums. This has been like this for the past 10 years. I can see no change when I look at the wear myself. My dentist has said that I now need to have 3 composite fillings to these teeth as they are nearly at the nerve and I cannot wait any longer. Last year I had my teeth bleached via this dentist with a home treatment that lasted 2 weeks (£300). I completed this treatment without having these teeth filled why if I have no pain, no decay, do I need to have them filled now? I did an overnight bleaching top-up only last week before visiting the dentist for my regular 6 month check without any problems. It is not the cost of the treatment, the fact that I do not want three new composite fillings to my teeth with all that goes with that. My dentist said that I must come in for these fillings as I cant wait any longer. I have no pain nor did I point out any problem to him the wear is the same as it has been for the past 4 years I have an electric toothbrush that stop if you apply to much pressure.So I cant see any change – I had x rays done before having the bleaching done they did not show-up any problems. Is this treatment from what I have said necessary?Is there no other treatment available? I have read about liquid plastic that forms a hermetic seal and seals the nerve. Do you know of this treatment or any other besides composite fillings.
