Because of the dry mouth I also tend to get many mouth ulcers, sore throat, sore gums and discomfort associated with dental work. I have been using Difflam Oral Rinse (Benzydamine hydrochloride) for the past few years. I use it as a rinse twice a day (rinse and gargle for around 40 seconds). I have found that it does stop pain and swelling and also helps with mouth ulcers.
