Hie.. For proper diagnosis need to have clinical evaluation of the same.. small bumps : how it looks like,...kindly share picture Sides of the tongue: cleanching of the teeth..Means u r closing your mouth too tight while sleeping.. u need to have nighy guard to wear for this.else it will lead to TMDs.. For red patch : need again a picture for thorough evaluation..

Small white bumps in inner cheeks can be because of lots of reasons. Sometimes it is a normal finding too. Though about the bumps in the lateral part of the tongue seems more of indentation of the teeth over the tongue. It is best to visit a dentist near you for proper history and clinical evaluation to reach a definitive diagnosis.

Give proper history. Since when you have this? Is it painful/painless? Do you have any habits? Do you have any medical condition? In picture they seem to be normal papillae of tongue.

Hi! Photo is not clear. *Still white bumps in both sides of cheek- if you meant by a while line front to back of the cheek then it's mostly because of cheek bite- which is normal. *Red patch of roof of the mouth- need photo. *Bumps on side of the tongue - mostly due to close contact with teeth which is very common. Above mentioned are not confirmed till a clear photo. Please do mention if there is any pain or increase in size of the bumps/ patches.
