A deep bite is a condition where your upper front teeth bite too deeply over the lower front teeth.

Although it may appear as merely an aesthetic issue a bad bite is in fact far more serious; it can lead to significant damage to the teeth and gums as well as headaches and temporomandibular joint (TMJ) disorders.

Missing back teeth in an adult can create or exacerbate a ‘deep bite’ . Out of all the bite disorders, a deep bite is the most detrimental to the teeth and health of the jaw joints. It also has an impact on facial aesthetics with wearing of the behind teeth reducing the facial height and increasing wrinkle lines and aged appearance.

Traumatic occlusion (or a bad bite) is the result of misalignment of the teeth and jaws, often caused by genetics, but can also be due to teeth crowding, bad, worn or decayed teeth, and poor or failing dental work and missing teeth, particularly missing back teeth. Habits such as thumb sucking, clenching or grinding teeth (bruxism) can also contribute to causing such problems.

DEEP BITE

A deep bite is a condition where your upper front teeth bite too deeply over the lower front teeth.

Why Treat A Deep Bite?

Unlike other diseases/dental conditions, which have an immediate symptom of pain, Traumatic occlusion and/or Deep bite is more of a silent disease as it results in a series of small seemingly insignificant changes which occur slowly over a period of time resulting in irreversible changes recognized first as an all of a sudden generalized sensitivity when most of the damage has already occurred.

Features Of Deep Bite

Initial stages: Common features to look for when you have deep bite in the initial stages would be:

• Wearing away of the top surface of the teeth commonly known as attrition
• Craze lines/thin fracture lines in the front teeth along with chipping if your teeth are weak even on minimal trauma
• If your teeth are strong then the stress is transferred to your gums causing accumulation of deposits and bleeding of gums mainly in the lower front teeth
• Excessive stress on TMJ – as the upper teeth bite totally over the lower teeth, the function of your teeth will be poor especially when chewing food
• The gum behind the upper teeth and in front of the lower teeth can be chewed away due to the top edges of teeth biting into the gums called gingival recession leading to the advance stage of deep bite and collateral gum diseases
• Bad breath may be noticed as a side effect of the gum disease and deposits in the teeth
• Some patients observe unclear speech due to reduced vertical height

Your smile can also be affected by this condition, as the upper teeth can wear on their chewing surfaces overtime, gums look un-aesthetic. This can be a very serious issue and often leads to loss of the front teeth.

Advanced stage: causes excessive wear to your teeth presenting as generalized sensitivity in all teeth and pain in severely affected teeth, gingival recession and TMJ pain (pain in jaw joints and muscles).

• If you have clicking sound or experience pain in the jaw while you open and close your mouth
• If you have a habit of grinding your teeth unconsciously
• If you feel fatigue after chewing for a while
• If you experience tiredness while talking for too long
• If there is bone loss present in your x-ray

Treatment Of Deep Bite By Cosmetic Crowns

A deep bite, even in adults ,can be easily corrected these days with one of the many effective restorative treatment options. Treatment involves raising the bite to establish a correct bite by placing crowns on the behind teeth and replacing any missing teeth so that the chewing forces are distributed equally. If front teeth are already damaged [worn /chipped], metal free crowns or laminates may be placed for aesthetics. Simple gum cleaning (scaling) may be required.

In advanced stages where patients come with pain, generalized sensitivity and gum recession (chewing away of gums); along with crowns on the back teeth, those teeth with pain may require root canal therapy and the front teeth will also require crowns. Additionally, gum surgery would be required where indicated.

Night guard (a protective template) is given more as a preventive therapy for monitoring in the earlier stages, when no damage has occurred as yet. Though it does not treat, it significantly delays the progress of the disease and prevents jaw joint (TMJ) and muscle pain from occurring. When detected at a younger age, before attrition of the teeth has occurred, it can be corrected by moving the teeth to a stable correct position using braces and/or anterior bite plane also called Orthodontic treatment.

Treatment Cost

The cost of the treatment depends on the quality of crowns we choose to increase the bite and number of teeth involved in raising the bite. Each crown would cost in the range of Rs7000 to 12000 per unit. The best suited crown for this would be zirconia monolithic crown which would cost Rs12000 per unit.

Correcting deep bite misalignment will not only improve the functionality of your teeth, but also make brushing and flossing easier – thus helping you to keep your teeth healthy. Of course it also dramatically improves the appearance of your smile too.

FAQs

But my lower teeth do not touch upper teeth do I still have deep Bite?
When you have a deep bite condition, your teeth may not touch in resting position but when you are eating the lower teeth hits the upper teeth constantly transferring all the pressure from your lower teeth to the upper teeth and vice- versa then to the gums and later to the TMJ.

Solution to this is bite rise using orthodontic treatment or cosmetic crown, where the crowns are designed in such a way that the bite is re-organised so that stress on the front teeth is averted.

How does deep bite causes TMJ Pain?
Deep bite puts unnatural stress on the muscle and joint over a period of time causing soreness and pain while performing normal function. This happens because of the constant stress which damages the bones and cartilage over a period of time.
