Brief answer: BURNING MOUTH SYNDROME DUE TO DRY MOUTH. Hi. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain and presentation of symptoms the sticking of teeth to the cheeks and lips on the inside is caused when the mucosa becomes dry and atrophied and it causes sticking of the teeth to the inner side of cheeks and gums and it occurs in a condition known as DRY MOUTH The dry mouth can occur due to a few conditions like side effect of medicines like that helps in reducing blood pressure, oral contraceptives,anti convulsants etc,infections like Thrush, Auto-immune diseases like Sjogrens Syndrome, Nerve damage that supplies salivary glands,diseases like HIV/AIDS, uncontrolled diabetes, cancer,surgical removal of salivary glands, clogged ducts of salivary glands, long standing dehydration etc.. This leads to a condition known as Burning Mouth Syndrome in which there is burning pain in mucosal surfaces of mouth and is seen many a times in patients with dry mouth.. The pain can be spontaneous and even on taking low spicy food there is burning in mouth.. The treatment of burning is dependent on treating the underlying cause like for dry mouth you should consult an Oral Physician and get evaluated and in case if you have any underlying cause of dry mouth get it treated.. For symptomatic relief you can take SALIVA SUBSTITUTES containing methylcellulose and can be instilled multiple times in mouth for lubrication.. SALIVA STIMULANTS like sugar free chewing gums can be chewed to stimulate saliva flow. Drug like PILOCARPINE can be taken as it helps in stimulating saliva flow and should be taken only after advise by a physician.. Sucking ice pops can help in relieving burning and pain in mouth.. Cold water gargles and gargle with a numbing mouthwash can help.. Avoid hot,spicy,sour and acidic foods.. Take a soft and bland diet.. Drink plenty of water preferably cool.... You should also limit the intake of tea,coffee and areated drinks Hope this information helps..
