Hi David,
For sensitive gums try the new Colgate Sensitive Pro Relief toothpaste. I had sensitive teeth and had been using Sensodyne without much effect, my dentist recommended the Colgate one (in fact gave me a sample tube). I must admit I was not convinced, but now having used it it works – rub a little on the sensitive areas and it really makes a difference. I also started using an electric brush rather than manual and my teeth and gums are now fine.
Glad to hear you are doing well – keep enjoying the beer!
Happy New Year, Jill
