Something you should be aware of when having teeth removed is that the act of applying pressure to the tooth signals your body to keep the bone density high behind the tooth, when you remove a tooth that pressure is no longer there and the density of the bone started to lessen.
Lose too many teeth and you start to lose the shape of your jaw.
If you have to lose a tooth it is a good idea to get it replaced as soon as possible. This is another reason implants are superior to dentures. Dentures don't put pressure on the bone, whereas implants do. https://pasadenaperio
