The Gingival Sulcus or Gingival Crevice is that little ridge in your mouth where your teeth meet your gums.

Just like a cuff of a sleeve fits against the wrist, the gum tissue in your mouth fits tightly around each of your teeth.

You can think of it as the space between the edge of the sleeve and the wrist, with the sleeve representing your gums and the wrist representing your tooth.

Moreover, keeping it clean is an important part of gum and tooth health.

With the help of good oral and dental hygiene, you can keep it clean. Furthermore, the more you know about your mouth, the better you can take care of it throughout your life.

This includes taking certain steps to prevent oral conditions like gingivitis or periodontitis.

Keep on reading to learn more about the gingival sulcus and how to keep it healthy as much as possible as a part of your daily dental hygiene habits.

Gingival Sulcus

The gingival sulcus is the relative space between each of your teeth and the gum tissues that surround it.

Moreover, it is a small, V-shaped groove around the base of your tooth.  At the bottom of the sulcus, there is a cementoenamel junction.

This area helps your gums to stay attached to the surface of your teeth.

When it is healthy, the gingival sulcus is snug around your teeth from the base of it all the way to when your tooth emerges from your gums.

This leaves very little room for any external substances like food, to enter this space between the gums and tooth.

On the other hand, if it is unhealthy or diseased, the pace between the sulcus and the tooth becomes a little larger.

Furthermore, it allows substances to enter the space more easily.

The gingival sulcus helps to protect your gums from infection or diseases.

In case your gums get diseases, you can experience problems that are related to both the tooth and the gums.

These include:

  • gums that pull away from your teeth
  • loose teeth
  • pain
  • changes in your teeth

Depth of Gingival Sulcus

One of the important things to understand is that a sulcus is between 1 and 3 millimeters, (mm) deep and is considered standard in most individuals.

However, any depth of more than 3 to 4 mm may be a sign of gum disease.

With time your gums changes and it often occurs due to inflammation and aging as well as individual differences in people.

But in every person, this relative depth of the gingival sulcus is an important part of assessing how healthy this area is.

Measuring the depth of the gingival sulcus helps your dental practitioners diagnose gum diseases and even evaluate treatment options.

An Opening for Gum Disease

It is crucial to thoroughly brush the area where your gums meet the teeth and floss between them to keep the entire gingival sulcus clean.

When you do not do so, you allow the plaque to build up on the gums at the base of a tooth, which can cause gingivitis.

Moreover, it can cause inflammation and irritated gums. Fortunately, you can reverse this condition with the help of good oral and dental hygiene.

However, if the plaque continues o build, the inflammation can lead to your gums detaching from the tooth, thus causing the space between the teeth and gums to deepen.

This deepening of the sulcus or development of a periodontal pocket is an early indicator of periodontal disease.

According to the National Institute of Dental and Craniofacial Research, periodontal disease classification is the site with gum attachment loss of at least 3 mm and a pocket depth of at least 4 mm.

It is important to note that gum diseases are common among Americans and half of the population over 30 years of age has periodontists.

While some of the risk factors are unavoidable due to genetics, age, medications, and medical history, other preventable risks are smoking, and unhealthy diet choices.

Examination of Gingival Sulcus

Your dentist will check your gums for disease during a regular dental exam. Moreover, they may order dental X-rays to evaluate or monitor bone loss.

To measure the depth of the gingival sulcus, your dentist will use a small ruler to gently probe your gums.

They will do so to check for signs of inflammation and measure the sulcus around each tooth.

Moreover, to do so, they will place the ruler just under the gum tissue.

There are 6 main areas in your gums i.e. Sextants, according to the British Society of Periodontology.

three of these belong to the maxillary arch i.e. your upper jaw, and the rest of the three belongs to the mandible, i.e. lower jaw.

These sextants are:

Top right, top anterior, top left, bottom right, bottom anterior, and bottom left.

After probing your gums, your dentist will note the highest score for each sextant in a range of 0 to 4.

0 means no gum treatment is necessary while 4 means the following:

  • oral hygiene instruction
  • cleaning treatments
  •  evaluation of whether more complex treatment is required
  • potential referral to a specialist

Conditions that can affect the Gingival Sulcus

Certain conditionals can affect the gingival sulcus. Thus, knowing more about them can help you to keep your gums healthy.

Gingival Hyperplasia

In gingival hyperplasia, there is an overgrowth of the gum tissue around your teeth.

Gingivitis and Periodontitis

Gingivitis is an inflammation of your gums, that usually occurs due to bacterial infection.

If you do not get treatment for this condition, it can even become a serious complication, i.e. Periodontitis.

bleeding gums

Food and plaque getting trapped in the sulcus can cause these conditions as well.

Red, tender, swollen gums, bleeding gums, loose teeth, pain while chewing food, dentures that do not fit, and bad breath that does not go away with brushing are symptoms of this condition.

Cavities

Cavities or decaying areas of the tooth that gradually form holes can also affect your gums and gingival sulcus.

A cavity in the root of your tooth, below the gums, can also affect the gums around the tooth.

Moreover, if the tooth decay is severe, pus can build up around the tooth because your body is reacting to and fighting bacteria.

Toothache, pain with cold, hot or sweet foods and drinks, visible holes or black spots on your teeth, and pain while biting down are symptoms of this condition.

Treatment Options

The treatment of this condition depends on the specific gum disease or tooth issues you have, however, maintaining good oral and dental hygiene for healthy gums and teeth is important.

Scaling: Scaling is a process through which your dentist will remove tartar from above and below the gum line.

Root Planing: In this process, a dental professional will smooth rough spots and remove plaque and tartar from the root of the tooth.
