Why are my teeth yellow

by

Common causes of yellow teeth include staining from beverages and food over time. Drinking coffee, tea, red wine or soda leaves behind pigments that dull enamel. 

Eating foods like tomatoes or dark berries can also stain.Not brushing properly allows plaque to build up. 

The bacteria in plaque produce acids and compounds that stain and degrade tooth structure. This leaves teeth looking yellowed.Certain medications administered as a child, such as tetracycline, may irreversibly stain developing teeth a yellow-gray shade. 

Genetics also influence how quickly teeth stain – some porcelain naturally than others.Other potential reasons are smoking, which leaves nicotine residue, and aging as enamel gradually wears away over decades.

Yellow teeth disease

Dental fluorosis is a condition that causes teeth to become yellow, brown or white-spotted. It occurs when young children consume too much fluoride from water or other sources as teeth are developing.

Excess fluoride is absorbed by teeth before they erupt into the mouth. This causes enamel to become improperly formed, resulting in staining or discoloration ranging from slight to severe.

Mild fluorosis appears as faint white spots only dentists may notice. Moderate cases show wider opacities or yellowing. Severe fluorosis has stained and Pitted enamel. It’s mostly a cosmetic concern.

Proper diagnosis from a dental exam determines the fluorosis level. Mild forms often need no treatment for health. Severe staining may use cosmetic bonding or veneers.

Are yellow teeth bad teeth?

Yellow teeth do not necessarily considered as weak teeth or bad oral health, but could be a sign of underlying issues if severe.

Mild yellowish staining is common and often only skin-deep on enamel. It may result from regular coffee/tea drinking or acidic foods over many years. These superficial stains usually do not harm teeth.

Deeper yellowing could indicate more advanced decay under restorations, poorly cleaned plaque buildup, or regression of receding gums. This level of staining raises risk of decay problems if left untended.

Seeing a dentist helps determine if underlying tooth or gum illness is present requiring treatment. Otherwise, whitening remedies can successfully restore smiles by lifting many natural or extrinsic stains causing yellowing. Mild cases do not always mean unhealthy teeth.

Why are my teeth yellow

  • Diet/Hygiene: Consuming colored/staining foods/drinks regularly without thorough brushing allows extrinsic stains to build up over years.
  • Smoking: Tobacco smoke and secondhand smoke contain chemicals that can affect enamel and increase yellowing.
  • Age: As we grow older, teeth tend to darken naturally to some degree as outer enamel layers wear away.
  • Medical conditions: Certain illnesses/medications like fluorosis, tetracycline use as a child, Wilson’s disease can intrinsically stain teeth.
  • Genetics: Some people are predisposed to more porous enamel that picks up stains more readily.
  • Stress: Teeth grinding/clenching from anxiety puts fillings, crowns at risk for staining.
  • Poor hygiene: Not brushing adequately at least twice daily and flossing daily allows plaque/tartar to accumulate, harboring bacteria.

Seeing your dentist can determine if staining is superficial or pointing to underlying issues like early cavities. Professional cleanings and whitening treatments are generally very effective at removing stains to brighten smile. Addressing causative factors like diet or hygiene habits can help prevent future discoloration.

Can yellow teeth be white again?

Yes, yellow teeth can often be whitened to a brighter shade. The degree of discoloration will impact results.

Surface stains caused by foods and drinks may be removed through over-the-counter whitening strips or trays using a low-level peroxide gel applied for a few weeks. This bleaches away many extrinsic stains.

Deeper intrinsic stains from issues like aging, medications or fluorosis may require professional in-office whitening treatments. 

A dentist can perform this using a higher concentration of peroxide applied directly to the teeth.Cosmetic options like veneers or crowns can transform severely stained teeth to a very white shade. 

These entirely resurface the teeth.Proper cleaning helps maintain results by preventing new stains. 

Yellow teeth vitamin deficiency

It’s usually not the yellow teeth alone that prompts testing for deficiencies, but other systemic signs/symptoms. 

Addressing underlying nutrient inadequacies along with professional dental care helps repair enamel damage and prevent further discoloration over the long-term.

Why are my teeth yellow near the gums

  • Gingivitis/periodontitis – Inflamed gums expose natural yellow root color.
  • Receding gums – Less gum coverage reveals more yellow root surface.
  • Tooth structure – Less enamel at gumline so more yellow dentin shows through.
  • Plaque buildup – Poor brushing allows bacteria/stains below gumline.
  • Age – Natural gum recession over time exposes yellow roots.
  • Smoking – Restricts blood flow, reduces gum protection and increases plaque.

Proper cleaning essential to prevent issues. See dentist if yellowing persists – May need cleanings/deep cleaning to remove stains fully for a brighter smile. Focusing on excellent home care habits long-term helps maintain whiter teeth overall.

Reasons for Yellow Teeth

Staining from Beverages and Food


Drinking staining beverages like coffee, tea, red wine and soda on a regular basis can cause teeth to take on a yellowish hue over time. The pigments and compounds in these drinks cling to teeth, building up layers of surface stains. Acidic foods like berries can also stain. Without proper brushing, these extrinsic stains set in.

Not Brushing Thoroughly Enough


Not removing dental plaque through daily brushing and flossing allows it to build up on teeth. Plaque harbors bacteria that produce acids and other compounds which can mar tooth structure and shade. This leads to a dingier, duller look.

Genetics and Aging


Some people’s teeth show signs of staining more quickly due to the density and architecture of their enamel. Likewise, over decades, natural wear and thinning of enamel through aging may expose the yellower underlying dentin.

Certain Medications


If antibiotics containing tetracycline are taken as a child while teeth are developing, it can irreversibly stain them gray or dark yellow. Dental fluorosis from too much fluoride during development also stains.

Smoking


The toxins present in cigarette smoke, such as tar, adhere to tooth surfaces causing long-term yellow staining that is difficult to remove.

Seeing a dentist helps identify the underlying cause of yellowing and recommend the best treatment to safely restore a brighter, whiter smile.

Can You Fix Yellow Teeth Naturally?

  • Baking soda + toothbrush – Mild abrasive scrubs surface stains
  • Lemon/lime juice – Acidity can act as natural bleach
  • Hydrogen peroxide 3% – Natural bleaching properties when swished
  • Oil pulling with coconut oil – Aims to dissolve stains in mouth
  • Activated charcoal paste – Absorbs stains when brushed on teeth
  • Clove oil – Mild bleaching properties when applied to teeth

However:

  • Effects are typically minor and only for light stains
  • Won’t treat underlying causes or deep staining
  • Enamel health risks with some (lemon juice)
  • Habits may still cause new stains

See dentist if stains are severe or persisting to identify cause and get professional treatment like bleaching for best results. Combining natural remedies with good oral hygiene helps maintain whiter teeth but has limitations vs dental work.

Key takeaways

Treatments – Cleanings remove surface stains; whitening lightens deep stains

Diet – Coffee, wine, berries stain without brushing

Plaque – Not brushing enables bacteria buildup

Medical issues – Fluorosis, meds like tetracycline yellow teeth

Age – Enamel wears, exposes sticky inner layers
