Does cavity on tooth make gum irritation also? can it be detected any parts of teeth? can it be fixed easily on any parts of teeth?

Lot of questions..: A cavity can also irritate the gum tissue, especially if it is near the gumline. For the most part, a carious lesion can be detected on any part of the tooth... That being said, some lesions escape detection due to their location. And finally, no, they can't always be easily fixed on any part of the tooth... Access is the key, and then placing the restorative material.

Yes and no.: Yes, a cavity down along the bottom of a tooth can cause gum irritation. However that may not be the whole story. If the gum is irritated as well, I have follow up questions, such as is there periodontal disease? Is the cavity so large that it is now effecting the pulp? Do you have a partial denture that may be causing more irritation in that area too? It all needs to be considered.

Sometimes, S.. S..: The cavity doesn't really irritate the gums, but food, plaque, bacteria, toxins caught in and around the cavity can. Detection is based upon visual and radiographic examination and larger ones are easily detected, although small ones, especially between teeth or around fillings are difficult or impossible to detect in early stages. 'easy' is subjective term. Some cavities filled easier than others.
