Why do I have fluid-filled gum swelling and metallic taste?

Question

Hello doctor,

Last night I went to bed after feeling fine all day, and when I laid down I got a horrible metallic taste in my mouth. When I felt the bottom gum right at the back there appeared to be a fluid-filled swelling on the top of the gum (there are no teeth in that part of my mouth), and when I looked this morning there seemed to be a whitish cream colored lesion on the inside of the gum and a couple of tiny ones on the top of the gum near to where the swelling is. I contacted my GP, who prescribed a mouthwash over a phone (Benzydamine), saying that it sounded like an ulcer with the constant metallic taste. It kept me awake the whole night. But I am not really sure if I have somehow burnt my gum without even knowing?

Hello,

Welcome to icliniq.com.

I read your query. The condition you wrote may be due to several reasons:-

1) Due to burning by hot drink is possible but usually, it is seen in the anterior (front) of mouth.

2) It can be aphthous ulcer which is normally seen in the mouth but they are painful.

3) Are you on any medication like antibiotics not specified in your question?

4) Ulcer may be due to some mouth dissolving medication which might have burnt that area.

5) It may be due to trauma by your toothbrush.

6) Any upper tooth impinging on that area can cause an ulcer.

7) Apply chlorhexidine gel twice or thrice daily locally.

8) Take a B-complex tablet or capsule twice daily for 10 days.

9) Take a proper diet and lots of water, avoiding extreme hot food or drinks.
