What causes small red dots with white centers scattered across roof of mouth?
Patient: i have small red dots with white centers scattered across the roof of my mouth. They are really sore. This doesn't feel like the strep I've had before and my lymph nodes aren't swollen. The dots aren't swollen or pussy or in my tonsils, just the hard roof of my mouth.  I had a cold for about a week and a half but my sore throat is better now. I used zinc and cough drops constantly over the course of the week - could these little sores be from irritation of the zinc and cough drops? I had an STD test for a Visa and I have no STDs. I am very healthy and don't smoke or drink. Doctor: Thanks for using Health Care magic.Read your query.Roof of the mouth or the palate can become sore or it can develop a burning sensation due to may causes which can include drinking or eating hot foods excessively,spicy foods,canker sores ,throat infections or any tooth problems.* Since you have a history of cold and cough ,this could have triggered the formation of this lesion.I would advice you to get your throat infection checked with the ENT surgeon and have it treated .Avoid too much of over the counter medicines.Avoid spicy and hot foods .Avoid irritating the lesions by using toothpicks or by hard brushing.Apply a dentogel /mucopain gel on the lesion two or three times a day,Take nutritious food and lead a stress free life.Hope this was helpful.Thanks and regards.
