A receding gum line happens so gradually it often is not noticed until a significant amount of gum tissue is lost.
Be aware of these five signs of receding gums and prevent further recession.
When gums recede, the roots of teeth can be seen. Teeth roots are a darker color and not as shiny as enamel.
When gums recede, teeth appear longer than normal. Gum recession inspired the saying "long in the tooth."
Severe gum recession causes space between the teeth. These spaces can be harder to keep clean since food is likely to get stuck more easily between your teeth. If you feel like there is always food stuck between your teeth it could be because of receding gums.
When gums recede, teeth are likely to become abfracted. Abfractions are small notches in the tooth where enamel has eroded away near the gum line.
Exposed tooth roots are sometimes sensitive to cold, sweets, or touch.
This condition allows roots to be exposed and roots don't have enamel protecting them, they are more sensitive and can be cavity prone.
Because there is no enamel, the root surface is softer and more vulnerable to toothbrush abrasion and damage from abrasive toothpastes. These areas are also more prone to tooth decay.
Be sure to use a non abrasive toothpaste. I have listed abrasivity scores for many toothpaste brands here.
Once gums recede they don't grow back, but gums can be restored with a procedure called a gum graft.
Knowing the cause, will help you stop receding gums from progressing.
Ask your dentist or hygienist if you have early signs of gum loss and consult your dentist to identify the cause.
