A filling can stay in place for years, sometimes a long stretch of years, but forever is a different story. Your mouth is a rough place for any repair. Teeth bite,

No, tendons attach muscle to bone, while ligaments connect bone to bone and help steady a joint. Plenty of people use “tendon” and “ligament” as if they mean the same thing. That mix-up is easy to make. Both are tough bands of connective tissue. Both sit near joints. Both can hurt like mad when injured.

Yes, a dental numbing injection can injure a nerve, but the risk is low and many altered-sensation cases fade over time.

Yes, a rare clotting syndrome tied to some older shots was linked to stroke, while current mRNA shots have not shown the same pattern. That question deserves a plain answer, not a slogan.
