Causes of Receding Gums
Numerous factors can cause gum recession, including:
Periodontal Diseases
These are gum infections, caused by bacteria, that destroy gum tissue and the bone that holds your teeth in place. Periodontitis, the more advanced form of gum disease, is a primary cause of gum recession.
The early stage of gum disease is often not painful; therefore, symptoms often go unnoticed. Left untreated, though, early symptoms can develop into periodontitis — a serious gum tissue infection.
Early stages of gum disease can be seen with minor symptoms, including:
- Red, swollen, or purple gums
- Gums that feel tender to the touch
- Bleeding gums
- Chronic bad breath
Genetics
Some people are more susceptible to periodontal disease than others. Studies show that 30% of the population may be predisposed to gum disease, even if they take good care of their teeth.
Brushing Too Hard
Brushing your teeth too aggressively or with improper technique can cause the gum tissue to wear away, leading to gum recession. Once the gums have receded, the tooth’s root surface (cementum) is exposed, and abrasive brushing can then wear away this surface and the enamel.
Poor Dental Care
Inadequate brushing, flossing, and rinsing can make it easy for plaque to turn into tartar, a hard substance that forms on and between your teeth. Tartar can only be removed by a professional dental cleaning.
If tartar has built up below the gumline and caused gum disease, your dental professional may perform scaling and root planing — a procedure that removes tartar from both above and below the gum line. This is different from a standard professional cleaning.
Hormone Levels
Changes in estrogen levels over a woman's life — such as during puberty, pregnancy, and menopause — can make gums increasingly sensitive and vulnerable to gum recession.
Hormones cause more blood flow to your gums, which leads the gums to overreact to different factors. High levels of estrogen and progesterone make women more sensitive to the presence of plaque.
Tobacco Products
Smokers and other tobacco users are more likely to develop sticky plaque, which can result in gum disease. Smoking causes a lack of oxygen in the bloodstream, and the infected gums do not heal well. This can eventually lead to receding gums.
Grinding and Clenching Your Teeth
Grinding or clenching your teeth puts excessive force on them, which can lead to gum recession.
Crooked Teeth or Misaligned Bite
When teeth don’t come together evenly, too much force can be exerted on the gums and surrounding bone, allowing damage to the gum tissue to occur.
Symptoms of Receding Gums
As receding gums progress over time, you may notice the following symptoms:
Long Teeth
One symptom is the visible lengthening of your teeth. When gums recede because of gum disease, teeth appear to be much longer than normal. Pockets can form due to gum recession, leaving you more susceptible to infections.
Exposed Roots
Exposed roots are another symptom of receding gums that can be extremely sensitive and uncomfortable. Root exposure usually happens because of gum disease or overbrushing, which is often attributed to incorrect brushing technique, hard bristles, or too much pressure.
Loose Teeth
If you have receding gums, you may notice loose teeth due to gum disease caused by bacteria accumulation under the gums around your teeth. As receding gums worsen, the gum pockets deepen.
