What can i do to treat tooth pain after getting composite filling into cavities?

Contact your dentist: Some sensitivity is normal after any restoration. Usually 2-3 days of decreasing sensitivity. Tylenol, (acetaminophen) aspirin, or Ibuprofen can be used for mild to moderate discomfort. But if the intensity of pain is more severe, you must contact your dentist and make arrangements to have it checked.

OTC pain meds: You should not have pain after composite fillings. Typically the pain is from the injection sites which goes away after a few days. In the meantime any otc pain medicine like Motrin should help. If you are having pain in the tooth it could mean the filling was really close to the nerve and a root canal may be needed, or the bite may be too high and needs to be adjusted.

Need to see Dentist: Please see the dentist who filled the tooth asap... One possibility is that the filling is high. A slight adjustment may resolve it completely. Or... The filling may be very close to the nerve. This can lead to a root canal or loss of your tooth. Aleve, (naproxen) advil, Motrin or for more holistic patients, arnica can be helpful to reduce swelling and pain temporarily.

Time frame: Newly placed composites in teeth can cause the teeth to be sore for awhile. If the pain persists, then I would get back to the dentist. If the filling was deep, and near the nerve, there could be a potential nerve involvement. Also, if the filling is high in bite (you are hitting the area first before the other teeth,) the filling may need to be adjusted.

Not normal: Not normal. See dentist for exam to figure out reason.

Depends: depends on the pain but it is common to have some sensitivity done after "most" fillings independent on what material or techniques was used. For slight to mild pain I would just use ibuprofen etc to handle any inflammation/pain. for moderate to severe I would still take the ibu but at max dose (800mg every 6hrs) and schedule with the DR that did the work asap....It could be simple bite issues
