Hi.. Can understand your concern.. As per your complain toothaches most commonly occurs due to deep cavities into the tooth leading to reaching of infection in the pulp which is a central part of tooth containing nerves and blood vessels. Once infection reaches the pulp pain is initiated.. This infection can also reach the underlying bone through root canals of tooth and lead to pus formation under the root tips which in-turn cause intense pain.. There may be other cause of toothache and that is any deep infection in gums which can also reach to the bone and the adjoining tooth is infected from the root side upwards. Any treatment can be initiated only after knowing the exact cause for your toothache as the treatment modalities depends on the type of problem causing tooth ache.. Medicines that can help you in relieving pain are IBUPROFEN OR KETOROL-DT but only painkillers cant provide you forever relief until the cause of toothache is treated and it needs antibiotics (like amoxicillin , augmentin etc ,only to be taken if not allergic and prescribed by a dentist)as well as any in office dental procedure required. I would like to tell you that dental fear is totally a misconception which every now and then people create for themselves as well as others.. A dentist always tries to cure your problems and all necessary measures like local anaesthesia are taken to carry out any dental procedure painlessly. So you need not to worry and consult a dentist so that he can do a clinical evaluation and find out the exact cause of pain by taking an IOPAR (x ray) and carry out proper treatment.. Hope your query is solved. Thanks an regards.. Dr.Honey Nandwani Arora.
