Hi.. Thanks for the query.. Well, it looks like there is formation of dental abscess leading to pus formation below the root tips of the tooth and it is putting pressure over the nerves leading to severe pain. You can continue taking Combiflam to reduce pain but it will give you only temporary relief. Once you can consult your Dentist you can get an x ray of the tooth done and if the tooth is in a condition to be saved then Root Canal Treatment can be done.. In case of gross decay extraction of tooth is advisable.. Both the treatments with be followed by antibiotics and painkillers.. As of now along with taking antibiotics and painkillers you can also apply clove oil over the tooth as it has sedative action and helps in pain relief.. Biting over a clove or a garlic can also help in relieving pain.. Hope this information helps.. Regards..
