Is there a possible way to heal dental cavities without drilling?

Yes: Some dentists use lasers or micro abrasion to remove small carious lesions.

Rarely: If the decay has not entered the second layer of the tooth called dentin and only in the enamel it could heal itself by using high Fluoride toothpastes. However, once the decay enters the dentin the caries must be treated.

OZONE treatment: It is not used in the United States very much but pumping ozone gas into the cavity can cause the cavity to heal arrest by killing the bacteria that live within the cavity. The hole will still be there though and it will take some time for the soft parts of the tooth to get hard again. The tooth will probably need a restoration if the cavity was large enough.

MI Paste Plus: If a carious lesion is limited to only the enamel (outermost) layer of the tooth and has not yet cavitated, if appropriate, your dentist may recommend that you try to remineralize the cavity using amorphous calcium phosphate plus fluoride. The most commonly used form of this med is mi paste plus which you can only get from dental offices.

Yes! sometimes: Small cavities can be "arrested" by the use of flouride toothpaste, flouride rinses and many professional products . The balance of ph and saliva can also play a role in arresting decay. Talk to your hygienst or dentist about these ideas!

Drilling: The procedure to remove an amalgam restoration involves drilling out the restoration with a drill.

Sometimes: There is a condition called 'eburnation' in which the decay hardens. It can occur with a drastic improvement in hygiene. There are gels on the market today which can help to regenerate enamel . You may have to look for a dentist who is aware of these products and their efficacy.

Air Abrasion: There is new technology we are all using that is called air abrasion which is like a miniature sandblaster that has a very small tip and uses a smaller particle abrasive dust to remove caries and damaged tooth structure, often without local anesthetics!
