Top 12 Common Teeth Problems

1. Tooth Decay (Cavities)

Tooth decay, also known as cavities or caries, is the most common dental problem worldwide. It occurs when bacteria in your mouth produce acid that eats away at your tooth enamel, creating small holes or “cavities”.

To prevent tooth decay:

  • Brush your teeth twice a day with fluoride toothpaste.
  • Floss daily to remove food particles between teeth.
  • Limit sugary and starchy foods and drinks.
  • Visit your dentist regularly for cleanings and check-ups.

If left untreated, cavities can lead to pain, infection, and even tooth loss. Your dentist can usually treat small cavities with fillings. Larger cavities may require crowns or root canals.

2. Gum Disease

Gum disease, also called periodontal disease, is an infection of the gums surrounding your teeth. It’s a major cause of tooth loss in adults. Early stage gum disease is known as gingivitis. If it progresses, it can turn into periodontitis.

Common signs of gum disease include:

  • Red, swollen, or bleeding gums
  • Bad breath that won’t go away
  • Painful chewing
  • Loose or sensitive teeth

The good news is that gum disease is largely preventable with good oral hygiene habits:

  • Brush your teeth twice a day
  • Floss every day
  • Use an antiseptic mouthwash
  • Don’t smoke
  • See your dentist regularly

Treatment for gum disease depends on the severity. Deep cleaning, medications, and in advanced cases, surgery may be needed.


3. Tooth Sensitivity

If you feel pain or discomfort when eating or drinking something hot, cold, sweet, or acidic, you may have tooth sensitivity. This occurs when the enamel that protects your teeth gets thinner, or when gum recession exposes the underlying surface (dentin).

You can reduce tooth sensitivity by:

  • Using a soft-bristled toothbrush and desensitizing toothpaste
  • Avoiding acidic foods and drinks
  • Using a mouthguard if you grind your teeth
  • Seeing your dentist for professional treatments like fluoride gels or dental sealants

4. Bad Breath

Bad breath, medically called halitosis, can be embarrassing. It’s often caused by the buildup of bacteria in your mouth. While mints or gum can temporarily mask the odor, they don’t address the root cause.

To combat bad breath:

  • Brush and floss regularly to remove food particles and bacteria
  • Clean your tongue with a scraper or soft-bristled toothbrush
  • Drink plenty of water to keep your mouth moist
  • Avoid tobacco products
  • See your dentist if bad breath persists, as it could indicate a more serious issue

5. Tooth Discoloration

Over time, teeth can become stained or discolored due to foods, drinks, tobacco use, aging, medications or injuries. While some stains are superficial and can be removed with whitening products, others are deeper and require professional treatment.


To keep your teeth white:

  • Limit staining foods and drinks like coffee, tea, and red wine
  • Quit smoking or using tobacco products
  • Practice good oral hygiene
  • Consider professional teeth whitening treatments

6. Cracked or Chipped Teeth

Teeth can crack or chip due to injuries, biting on hard objects, grinding, or simply aging. Small chips may not cause pain, but larger cracks can be painful and lead to infection if left untreated.

If you have a cracked or chipped tooth:

  • Rinse your mouth with warm water
  • Apply a cold compress to reduce swelling
  • Cover any sharp edges with wax paraffin or temporary dental cement
  • See your dentist as soon as possible for proper treatment

Treatment options depend on the extent of damage and may include:

Damage Possible Treatment
Minor chip Bonding or filling
Larger chip or crack Crown or veneer
Severe crack or split Root canal or extraction

7. Impacted Wisdom Teeth

Wisdom teeth, also called third molars, are the last teeth to develop, usually in the late teens or early 20s. Sometimes, there isn’t enough room for them to emerge properly, causing them to become impacted. This can lead to pain, swelling, infection, and damage to nearby teeth.


Signs of impacted wisdom teeth include:

  • Pain or swelling in the back of the mouth
  • Difficulty opening your mouth
  • Bad breath or unpleasant taste

If you suspect you have impacted wisdom teeth, see your dentist. They may recommend removing them to prevent further issues. The removal process is a common surgical procedure done under anesthesia.

8. Teeth Grinding (Bruxism)

Teeth grinding or clenching, known as bruxism, often occurs during sleep. Over time, it can wear down tooth enamel, cause jaw pain, and lead to other dental problems. Common causes include stress, anxiety, sleep disorders, or misaligned teeth.

If you grind your teeth:

  • Wear a mouthguard at night to protect your teeth
  • Practice stress-reducing techniques like meditation or exercise
  • Avoid caffeine and alcohol before bedtime
  • See your dentist for further evaluation and treatment

9. Misaligned Teeth

Teeth that are crowded, crooked, or out of alignment can affect your bite, speech, and appearance. They can also make it harder to clean your teeth properly, increasing the risk of tooth decay and gum disease.


Orthodontic treatments can correct misaligned teeth at any age. Options include:

  • Traditional metal braces
  • Clear ceramic braces
  • Clear aligners (e.g., Invisalign)
  • Retainers

Your dentist or orthodontist can determine the best treatment plan for your individual needs.

10. Oral Cancer

Oral cancer includes cancers of the lips, tongue, cheeks, floor of the mouth, hard and soft palate, sinuses, and throat. It’s most common in people over 40, but can occur at any age. Risk factors include tobacco use, heavy alcohol consumption, and HPV infection.

Symptoms of oral cancer may include:

  • Persistent sores or lumps in the mouth
  • White or red patches on the gums, tongue, or lining of the mouth
  • Unexplained bleeding, pain, or numbness in the mouth
  • Difficulty chewing or swallowing

Early detection is key to successful treatment. See your dentist immediately if you notice any unusual changes in your mouth. Regular dental check-ups can also help catch oral cancer early.


11. Tooth Erosion

Tooth erosion is the gradual loss of tooth enamel due to acid attack. This can be caused by frequent consumption of acidic foods and drinks (like citrus fruits, sodas, and sports drinks), GERD (acid reflux), or frequent vomiting.

To prevent tooth erosion:

  • Limit acidic foods and drinks
  • Use a straw when drinking acidic beverages to minimize contact with teeth
  • Wait at least 30 minutes after eating or drinking something acidic before brushing your teeth
  • Chew sugar-free gum to stimulate saliva flow, which helps neutralize acid

If erosion is severe, your dentist may recommend bonding, crowns, or veneers to protect your teeth.

12. Dry Mouth

Dry mouth, or xerostomia, occurs when your salivary glands don’t produce enough saliva. This can be caused by certain medications, medical conditions, radiation therapy to the head or neck, or simply aging. Saliva is important for neutralizing acid, washing away food particles, and preventing tooth decay.

Symptoms of dry mouth include:

  • Sticky or dry feeling in the mouth
  • Difficulty chewing, swallowing, or speaking
  • Dry, cracked lips or tongue
  • Bad breath

To relieve dry mouth:

  • Drink plenty of water throughout the day
  • Chew sugar-free gum or suck on sugar-free hard candies to stimulate saliva flow
  • Use an over-the-counter saliva substitute
  • Avoid tobacco, alcohol, and caffeine, which can worsen dryness
  • Talk to your doctor if you suspect a medication is causing your dry mouth


  1. How often should I see the dentist? Most people should see the dentist every six months for a regular check-up and cleaning. However, some people may need to go more or less often depending on their individual needs.
  2. What’s the best way to whiten my teeth? The most effective way to whiten teeth is with professional treatments from your dentist, such as in-office bleaching or custom take-home trays. Over-the-counter whitening products can also help, but may not be as strong or long-lasting.
  3. What should I do if I have a dental emergency? If you have a severe toothache, broken tooth, or other dental emergency, contact your dentist immediately. Many offices have emergency slots or after-hours numbers. If you can’t reach your dentist, go to the nearest emergency room.
  4. Are electric toothbrushes better than manual ones? Both electric and manual toothbrushes can effectively clean your teeth if used properly. Electric toothbrushes may be easier for some people to use and can provide additional features like timers and pressure sensors. Ultimately, the best toothbrush is the one you’ll use consistently and correctly.
  5. Can I still get cavities if I brush and floss regularly? While brushing and flossing are crucial for preventing cavities, they aren’t a guarantee. Other factors like diet, genetics, and certain medical conditions can also play a role. That’s why regular dental check-ups are important, even if you have good oral hygiene habits.


We covered a lot of ground in this article! By now, you should have a good understanding of the most common teeth problems and how to prevent them. Remember, the key to a healthy smile is a combination of good oral hygiene habits at home and regular visits to your dentist.
