Recession and Abrasion

What is recession?

Recession is when the gums that is attached to your teeth experience a type of “trauma” that causes the gums to recede leaving a longer looking tooth, most often with the root of the tooth exposed. This is frequently exacerbated by a mechanical force; the toothbrush or anatomical factors of the teeth and gums. Unfortunately the gums are not able to grow back.

How it occurs?

Recession can be caused by many external and internal factors including:

  • Age
  • Anatomical factors/ tooth malpositioning
  • Quality of your gingiva
  • Tooth brushing technique
  • Force and pressure of brushing
  • How often one brushes
  • Type of toothbrush
  • Brushing technique
  • Abrasive toothpaste
  • Periodontal disease

What is abrasion?

Abrasion is tooth wear as a result of a foreign substance that mechanically abrades the tooth.

Most often is also caused by excessive brushing with a hard bristle type brush. Over time the wear caused by bad brushing habits causes the tooth to look longer and roots become exposed and loss of tooth structure.

When the roots are exposed they become hypersensitive and prone to decay, as is easier to trap plaque and food debris in these areas of abrasion and recession. Unfortunately the loss tooth structure is unable to return.

How it occurs?

  • Tooth brushing technique
  • Force and pressure of brushing
  • How often one brushes
  • Type of toothbrush
  • Brushing technique
  • Abrasive toothpaste

Symptoms

Recession and abrasion have similar symptoms as they both have similar precipitating factors.

These which include:

  • Hypersensitivity
  • Root exposure
  • Tooth structure loss near the gum margin

Treatment

Treatment varies depending of the severity of the recession and abrasion. However the best treatment method is to prevent further damage by having proper tooth brushing technique.

  • If the abrasion is severe a filling may be done to cover up and replaced the lost tooth structure.
  • Regular check-up and cleans to prevent inflamed gums
  • A soft tissue graft with a dental specialist to replace the lost gum tissue

Prevention

Unfortunately recession most often is unavoidable depending on your gum health and genetic factors. However you are able to prevent them from worsening with good oral hygiene and proper brushing techniques.

These techniques below are to help prevent the occurrence of abrasion and exacerbation of recession.

  • Brushing with a soft toothbrush
  • Brushing without extra force
  • Using an electric toothbrush with a pressure sensor
  • Limit use of abrasive toothpastes
  • Do not use a scrubbing motion
