Wondering how to prevent yellow teeth? Teeth can turn yellow for a variety of reasons but luckily, there are several ways to maintain that sparkling white smile. Here are some tips on how to prevent yellow teeth.

Yellow Teeth: Causes and Treatments

Why are your teeth turning yellow?

Beneath the enamel on our teeth is a naturally yellow substance called dentin. This is why the yellowing of teeth is more common in older people as their enamel wears away. Why else do teeth turn yellow? Potential causes include:

  • Improper brushing and flossing habits.
  • Stains due to the use of tobacco products.
  • Frequent consumption of coffee, red wine, tea, and dark colas that stain the teeth.
  • Medications such as certain antibiotics and antihistamines.
  • Certain diseases and treatments of those diseases.
  • Excessive fluoride in your water.

At-home tips for whiter teeth

The most basic weapon against yellowing teeth is proper daily dental care habits. This includes brushing twice a day for at least two minutes, flossing, and using a mouth rinse. Here are some other ways to prevent yellow teeth:

  • See your dentist for a check-up and cleaning at least twice a year. Discuss any medications taken regularly to determine if any of those medications contribute to yellowing teeth.
  • Avoid dark, staining beverages or remember to brush and floss right after consumption.
  • Avoid smoking or use of other tobacco products.
  • Brush with whitening toothpaste and use whitening mouthwash.
  • Over-the-counter whitening methods such as strips or mouth trays with whitening gel.

What can the dentist do to help?

Talk with your dentist about any concerns regarding discoloration of your teeth. He or she will suggest the most appropriate plan of action based on the severity of tooth discoloration. They will also be able to diagnose any underlying issues that could be causing the discoloration. Several options are now available for whitening and preventing future yellowing such as:

  • At-home dental whitening kits provided by your dentist, typically involving a bleaching gel and mouth trays
  • Whitening treatments in your dentist’s office, often utilizing a whitening agent combined with heat or light.
  • Veneers – thin tooth-colored shells fitted over top of the existing tooth.
  • Bonding – application of a tooth-colored resin that hardens on the surface of the existing tooth.
  • Specific treatments for yellowing teeth that have undergone a root canal.
