Tooth bonding black spot (photo)

The black spot on your bonded tooth could be due to several reasons:

1. Tooth Decay: This is a common cause of discoloration and can occur if plaque and bacteria have built up on your teeth.
2. Staining: Certain foods, drinks, or tobacco use can cause staining on your teeth.
3. Improper or failing Bonding: Even if composite material was properly applied, there could over time be leakage and discoloration.
4. Tartar Buildup: Accumulation of tartar on your teeth can also cause dark spots.

It's important to consult with your dentist to determine the exact cause and get appropriate treatment.

Additionally, please note that composite bonding does not last as long as porcelain veneers. Composite bonding typically lasts for a few years, whereas porcelain veneers can last much longer with proper care.

Hello,The composite may have been damaged. The exposed area might have discolored over time or may have started to decay. This is a condition that can occur over time with composite bonding treatment. Laminate veneers can be used for many years, whereas such issues may occur with composite bonding.

From what you're describing, the black spot on your bonded tooth could be due to a few common reasons:
Staining: Bonded teeth can pick up stains over time from food, drinks (like coffee, tea, or wine), or smoking. The bonding material is not as stain-resistant as natural enamel.
Decay Under the Bonding: If there’s a small gap or the bond has started to wear down, bacteria can get underneath and cause decay. This would appear as a dark spot.
Material Breakdown: Bonding materials can sometimes discolor or degrade slightly over time, especially if they’re exposed to a lot of staining agents or acidic foods.
What You Can Do:See a Dentist: The best step is to have your dentist examine the tooth. They can determine if it’s a surface stain, decay, or a bonding issue.Polishing: If it’s just a surface stain, your dentist can polish the bonding to remove it.Touch-Up or Replacement: If the bonding has worn down or if there’s decay underneath, your dentist might need to replace or repair the bonding.
