FAQs
The posterior teeth, including molars and premolars, primarily chew and grind food. They are essential for oral function and are located at the back of the mouth. However, their location and pressure make them susceptible to varying dental problems. This blog explores the common conditions affecting posterior teeth, their causes, treatment options, and preventive tips.
What Are Posterior Teeth?

Common Posterior Teeth Problems
1. Tooth Decay (Cavities)
Tooth decay is one of the most common problems in the dentition of posterior teeth. The pits and grooves on the chewing surfaces of molars and premolars might retain food and bacteria and develop plaque. Over time, accumulated plaque produces acids that erode the enamel, leading to cavities.
2. Gum Disease
Gum disease, or periodontal disease, affects the tissues surrounding the last teeth at the back of your mouth. Poor oral hygiene allows plaque accumulation along the gum line, leading to inflammation, bleeding, and, eventually, recession. Finally, untreated gum diseases would damage the bone supporting your teeth.
3. Cracked or Fractured Teeth
The posterior teeth are constantly under pressure while chewing, and it might crack or break. It is also caused by biting on hard objects, teeth grinding (also known as bruxism), or even trauma. Cracked teeth can be painful, and may require immediate dental care.
4. Impacted Wisdom Teeth
Third molars (or wisdom teeth) are the last set of teeth to erupt at the back of the mouth. There is usually not enough space for the teeth to grow within the jaw, causing impaction. Impaction can cause pain, swelling, and may negatively affect adjacent teeth.
5. Tooth Sensitivity
Dental sensitivity on the posterior teeth can result from enamel erosion, gum recession, or cavities. It often triggers sensitivity to hot, cold, or sweet foods and beverages, making eating uncomfortable.
6. Dental Abscess
A dental abscess is a pus-filled cavity caused by bacterial infection. It can occur at the root of the posterior tooth due to decay or trauma when left untreated. Abscesses are painful and can lead to serious complications if not treated properly.
Causes of Posterior Teeth Problems
1. Poor Oral Hygiene
Poor brushing and flossing habits result in plaque and bacteria build-up over the posterior teeth. Hence, it causes decay, gum disease, and other dental problems.
2. Diet Full of Sugary Foods
Frequent intake of sugary or acidic foods and beverages can demineralize the enamel and increase the risk of cavities. Sticky foods could easily leave remains on the grooves of posterior teeth.
3. Teeth Grinding

Bruxism or teeth grinding or clenching, especially at night, puts a lot of pressure on the posterior teeth. Such habits often lead to cracks, fractures, and wear and tear of the enamel.
4. Misaligned Teeth
Teeth that are crooked or crowded make it difficult to clean the back of the mouth properly. In this case, the risk of plaque buildup and decay increases.
5. Lack of Regular Dental Appointments
Neglecting to go for checks on a regularly scheduled basis results in late detection and treatment of posterior teeth. Regular checkups are essential for maintaining oral health.
6. Damage or Injury
Accidents or injuries to the mouth can damage posterior teeth causing cracks, fractures, or even tooth loss.
Treatment Options for Posterior Teeth
1. Fillings for Cavities
If tooth decay is detected early, it can be treated with a dental filling. A decayed portion is removed and the cavity is filled with a durable material such as composite resin.
2. Root Canal Treatment
Root canal treatment is needed for very severe decay or infection. The process involves removing infected pulp from the tooth, cleaning the root canal, and sealing it to prevent further damage.
3. Dental Crowns

Cracked or severely damaged back teeth can be restored with dental crowns. Crowns are caps made to measure that cover the whole tooth for strength and protection.
4. Tooth Extraction
A posterior tooth can be extracted under circumstances of severe damage or impaction. Wisdom teeth are commonly extracted to prevent potential problems.
5. Gum Disease Treatment
Scaling and root planing are deep cleaning procedures that act against gum diseases. Highly advanced conditions may impart surgical intervention.
6. Dental Implants or Bridges
If a posterior tooth is lost, it can be fixed with an implant or a bridge. The restoration of function provided by these two options prevents any possible shifting by the adjacent teeth of the enamel or recession of the gum.
7. Sensitivity Treatments
Desensitizing toothpaste, fluoride treatment, or dental bonding can reduce teeth sensitivity caused by enamel erosion or gum recession.
Prevention Tips for Posterior Teeth Problems
1. Brush and Floss Regularly
Brush twice a day with fluoride toothpaste and floss between the teeth to ensure that plaque is removed from between your teeth and below the gum line.
2. Use Night Guard for Bruxism
Wear a custom night guard in case of teeth grinding while sleeping.
3. Balanced Foods
Limit, fruits, vegetables, and dairy products while reducing intake and acidic sugars to strengthen teeth.
4. Regular Visits to Dentists
These ensure regular biannual dental cleanings and examinations for early problem detection and treatment.
5. Dental Sealants
Even so, these are thin coats applied on the chewing surfaces of the back teeth to guard them against cavities. These are specifically for children and teenagers.
6. Avoid Using Teeth as a Tool
Don't use your teeth to open some packages or bite them on hard objects because such things may cause cracks or fractures in your teeth.
7. Hydration
Water flushes the food particles, bacteria, and lowers the risks of decay and gum diseases.
