Boy Nelie I have some of the same issues as you. Regular toothpaste burns and so does beer. I can do without the toothpaste but beer??? Actually Guinness is ok. I seem to have a "hot spot" on my tongue, lower left side that is affected by certain foods and toothpaste and hot, as in temperature, foods. Most taste is back, chocolate just recently but not completely, and only milk chocolate. Check out Dental Depot website for biotene products. I use the oral jel at bed time. Darn dry mouth. Finished my 35 rads and 7 chemos in Sept
