I would still go and see the dentist and get the shots done.
Something has changed if its just appeared.
Remember as a kid a lad at school suddenly started getting epilepsy and the epilepsy docs where straight in with that diagnosis.
5 years later a visiting family friend from NZ MD was asking about if the Brain scan had shown anything etc. What no scan?
They paid for one privately and bloody great tumour was found.
The docs don't like dentists for some reason. The guy that ripped that tooth out of mine was a hospital dentist type would as far as a could tell was basically a mandible ortho surgeon linked with being a pain specialist. He was contracted by my dentist to do all the extractions, wisdom teeth and the like which he removed three of mine in the one sitting in 45 mins under a local.
Old George said he had through out his career had his doubts about these hospital types and their snooty superiority. That lad had been short of cash and approached him to get some extra work. Two sessions later he was doing all the extractions and wisdom teeth. George who had been a dentist for 30 odd years said he felt like an amateur watching him. And his post extraction complications list was 10% of what it used to be.
