Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that numbness of the roof of mouth can be secondary to inflammation over the roof of mouth and can be due to burping that might be bringing acid along with it causing
acid reflux..
Acid irritation of roof of mouth seems to be a cause in your case..
I would suggest you to consult an Oral Physician and get evaluated and he can do a thorough clinical evaluation and rule out the cause and treat accordingly..
You can be advised to do warm saline gargles, take Vitamin B complex supplements and suck ice..
Drink plenty of water and maintain a good
oral hygiene..
In case if you have acid reflux you can be advised to take
Proton Pump inhibitors like
Omeprazole, antacids like
Milk of magnesia,, H2 blocker like Ranitidine, taking small portions of food every 2 hours and do moderate workout..
Hope this information helps..
Thanks and regards.
