Symptoms: Your gum margins are swollen, red and bleed when you brush your teeth.
This can still be done even if your tooth has snapped off or has had to be removed right at the gum margin. Then, three or four posts are drilled into what is left of the tooth so the cap or crown can be fitted to them.
It's usually done by filing the tooth away to form a "peg" on to which the cap is cemented and can still be done even if your tooth is snapped off at the gum margin.
