<s>[INST] The gums under my front two bottom teeth are lower than the rest of my gums, but this is not the problem... every now and then for a few days at a time, the lower part of my exposed teeth and the gums below them get really sensitive and when I take a deep breath I feel not pain exactly, but discomfort that swells during the breath and then disappears. However this happens every time I take a deep breath and eventually after a few days it goes away. Any suggestions? [/INST] Hello, Welcome Thanks for consulting Chat Doctor I have gone through your query, you feel sensitivity in lower front jaw as there is Reccesion of gingival that's why you feel sensitivity don't worry about this you should go to dentist and go for Scaling and Root planning.  For temporary relief you can do warm saline gargle two - three times a day Do chlorhexidine mouthwash 2 times a day Hope it will help you. </s>
