  • Cavities and tooth decay: Caused by a buildup of plaque and bacteria, cavities are the most common dental problem, affecting over 90% of adults. Cavities can be avoided with good oral hygiene and routine dental checkups.
  • Gum disease: Also known as gingivitis or periodontitis, gum disease is an infection of the gums that can lead to bone loss and tooth loss if left untreated. Around 47% of adults over 30 have some form of gum disease.
  • Tooth sensitivity: The dentin beneath the worn-down tooth enamel can become sensitive to hot, cold, or sweet foods. Avoiding acidic foods and using desensitizing toothpaste can be helpful.
  • Cracked or chipped teeth: Teeth can crack or chip due to biting hard foods, teeth grinding, or trauma. This can cause pain and require treatments like bonding, crowns, or extractions.
  • Impacted wisdom teeth: When wisdom teeth are unable to fully emerge, they can become impacted and cause problems like pain, infection, and damage to neighboring teeth. Removal is often necessary.
  • Oral cancer: While less common, oral cancer can develop on the lips, tongue, cheeks, or throat. Regular dental exams can help detect it early.
  • Tooth Discoloration (Yellow Teeth): Staining from foods, drinks, smoking, or medications can discolor teeth. Professional whitening treatments or at-home whitening products can help restore a brighter smile.
  • Bad Breath (Halitosis): Persistent bad breath can be caused by poor oral hygiene, dry mouth, certain foods, smoking, or underlying medical conditions. Improved brushing, flossing, and dental cleanings are the first line of defense.
  • Temporomandibular Disorders (TMD): Problems with the jaw joint that can cause pain, clicking, and difficulty opening the mouth. Requires diagnosis and treatment by a dentist.

Maintaining good oral hygiene through brushing, flossing, and regular dental visits is key to preventing most dental problems. Seeking prompt treatment from a dentist is also important to address issues before they worsen.

  • Poor brushing and flossing techniques
  • Badly crooked teeth that are difficult to clean
  • Risk factors like tobacco use, pregnancy, and diabetes

  • Gum disease
  • Root infection
  • Cracked or broken teeth
  • Worn-down crowns or fillings
  • Enamel erosion
  • Receding gums

  • Poor oral hygiene
  • Dry mouth
  • Medication
  • Infection
  • Acid reflux
  • Certain foods like garlic and onions

Other common issues like toothaches, bleeding gums, gum recession, and missing teeth can also be caused by a variety of factors related to dental hygiene, injury, disease, and genetics. Orthodontic problems are all preventable and treatable with regular dental visits.


Maintaining good oral hygiene is key to preventing common dental problems. This includes:

  • Brushing your teeth twice a day with a soft-bristled toothbrush and fluoride toothpaste
  • Flossing at least once per day to remove plaque and food particles between teeth
  • Using an antibacterial mouthwash to kill bacteria and reduce plaque
  • Replacing your toothbrush every 3-4 months
  • Eating a healthy, low-sugar diet to prevent tooth decay

  • Visiting your dentist regularly (1-2 times per year) for cleanings and checkups

  • Parents should wean children off bottles by age 1 and avoid putting them to bed with bottles to prevent early childhood caries
  • Women should be extra vigilant about oral hygiene during hormonal changes like menstruation, pregnancy, and menopause
  • People taking certain medications that cause dry mouth should drink more water and use saliva substitutes

By practicing good daily oral hygiene and seeing a dentist regularly, you can effectively prevent most common dental problems like cavities, gum disease, bad breath, and stained teeth.

Best strategies to keep kids teeth from Decaying

The best ways to prevent tooth decay in children are:

  • Use fluoride toothpaste and a soft-bristled toothbrush to brush your teeth twice a day. Use only a small smear of toothpaste for children under 3 and a pea-sized amount for ages 3-6.
  • Floss daily starting at age 2.
  • Limit sugary and starchy snacks that stick to teeth and feed bacteria. Choose non-sticky, non-starchy snacks instead.
  • Throughout the day, sip on lots of water to flush away food particles. Steer clear of sugary beverages like soda, juice, and sports drinks.
  • Wean children off bottles by age 1 and avoid putting them to bed with bottles, as the sugary liquids can pool around the teeth and cause decay.
  • Use a fluoride supplement if you live in an area without fluoridated water. Find out from your dentist how much is appropriate for your child.
  • Apply dental sealants to the back teeth’s chewing surfaces. Sealants act as a barrier to prevent bacteria and food from settling into the grooves of the teeth.
  • Take your child to the dentist regularly starting by their first birthday for cleanings and checkups to spot and treat early signs of decay.
  • Avoid sharing utensils, cups or kissing your child to prevent transferring cavity-causing bacteria from your mouth to theirs.
  • Look in your child’s mouth regularly to spot early signs of chalky white spots or brown areas that may indicate decay.

By practicing good daily oral hygiene, limiting sugary foods and drinks, and seeing a dentist regularly, you can effectively prevent most tooth decay in children.


1: Are dental X-rays safe and needed?

Dental X-rays are safe and needed to diagnose problems like cavities, gum disease, and tumors. Modern digital X-rays use much less radiation than in the past. You can expect X-rays during your first exam after not seeing a dentist for a while, and then about every 2 years.

2: How do fillings work?

Fillings are used to close cavities that have broken through the tooth enamel. Your dentist will numb the area, drill out the decayed part, and then fill the cavity with a strong material like a composite resin. Fillings can last a long time but may need to be replaced if they wear down.

3: What are sealants and how do they help?

Sealants are a protective coating painted onto the chewing surfaces of the back teeth to prevent cavities from forming in the natural cracks and grooves. They are commonly applied on children’s teeth from ages 6-12, but adults can get them too.

4: What’s the best way to whiten teeth?

Over-the-counter whitening products and take-home kits from your dentist can help, but professional whitening treatments done in the dental office are the most effective. Before using any whitening products, especially if you have dental work or dark stains, consult your dentist.
