What are the reasons for the blackening of the tooth coating?

One of the frequently asked questions about dental veneers is: “Why do dental veneers turn black?”. This is a common problem that people face after wearing dental veneers for several years. If you don’t want the condition of your veneers to worsen, you need to identify the problem that caused the veneer to turn black and then fix it immediately. To treat the problem, it is very important to accurately identify its cause. To treat this problem, the intervention of a dentist is needed. The common causes of blackened veneers can be due to poor veneer adhesion, the use of cheap dental veneers, and other factors.

In this article, more details are mentioned about this:

Why does the dental veneer turn black?

If you suddenly notice that the veneers on your teeth have turned black, you should see your dentist immediately. Although your dentist will tell you exactly why, the most common causes of problems with dental veneers include:

  • Poor adhesion or improper installation
  • Cheap or non-standard materials
  • Gum recession
  • Abrasion of tooth enamel
  • Damage to the top layer of tooth enamel
  • Referring to newbies and non-experts

Poor adhesion or improper installation

The biggest sign of tooth enamel discoloration is a black line that appears near the gums. This happens when the crowns are not properly fitted and there is a gap between the gum line and the crown. In this situation, bacteria accumulate in this space and form a black line. This is a sign that your dental crown is installed improperly, and if you do not pay attention to this issue, more problems will arise. In addition, this black line is formed due to the entry of food under the veneer of the tooth. It is better to visit your dentist and find the exact reason for this problem.

Using cheap or non-standard materials

Sometimes the reason for the blackening of the dental veneer is the use of cheap and non-standard materials. Porcelain is the best option for dental veneers. Because it is thin and resistant and more similar to natural teeth. Other materials, such as composite porcelain, degrade quickly and thin at the edges. When the edges of the veneer are thin, the metal base is exposed and affects the appearance of the teeth.

Gum recession

Gum disease or periodontitis and severe tooth decay can lead to gum recession. When the gums recede, a space forms between the gums and the crown of the teeth. Bacteria and food particles can accumulate in this space and form an undesirable black line. This has severe effects on your smile and requires immediate dental attention. In such a situation, treatment of gum disease and severe tooth decay is necessary for long-term dental veneers.

Abrasion of tooth enamel

Tooth enamel begins to deteriorate faster due to lack of oral hygiene, smoking, alcohol consumption, or improper diet. When the bottom layer of tooth enamel is exposed, the color of the teeth becomes darker. Your crown may appear dark due to the darkening of the teeth behind it. Sometimes, the only way to treat this problem is to use a new tooth cover or to whiten the original teeth.

Damage to the top layer of tooth enamel

Dental veneers are thin shells with a sensitive structure. The upper layer of the tooth coating can be damaged if you do not follow the care tips, or if you use hard food. The damaged upper layer may cause dark spots that are easily recognizable on the tooth. You need to see a dentist to check the reason for the darkening of your dental veneers. If the cause is damage to the top layer of the dental veneer, there is no other way to treat it except to replace the dental veneer.

Referring to newbies and non-experts

Since dental veneers double the beauty of your smile, their installation requires advanced training. It is very important to choose an aesthetic and reliable dentist for dental crown installation. Getting dental veneers from untrusted and unknown dental centers can change the color of the veneers. So we advise you to do thorough research before choosing a clinic.

What methods can be used to reduce the darkness of dental veneers?

If you have noticed that the coating of your tooth has changed color to black, it is better to visit your dentist. The good news is that there are ways to treat this problem. Based on your symptoms, the dentist can use the following methods:

Dental bonding

It is an inexpensive treatment to hide dental defects. If the problem is only related to the appearance of your teeth, bonding can be effective. But if your crown is black due to a deeper problem, bonding may not work. If the problem is behind the veneer, the blackness may reappear. In this situation, it is better to consult your dentist to find out if this method is effective for you or not.

Replacement of dental veneers

Sometimes, if the dental veneers are blackened due to a complex problem, the only way to treat and solve the problem is to replace the dental veneers. Replacing new dental crowns may cost more, but it will make a significant difference. If you need dental veneer replacement and you have a valid warranty for your previous dental veneers, the cost of replacing new dental veneers may be lower or even free for you. It is best to contact your insurance provider or dental clinic to confirm the cost of the service.

Natural teeth whitening

If the veneer has turned black or gray due to darkening of the back teeth, natural teeth whitening can improve the dark appearance of the veneer. However, it is not recommended to whiten the veneer. Because bleaching may damage the tooth enamel. Considering that dental veneers are thin and sensitive, it is necessary to follow special care tips to avoid problems.

Cleaning dental veneers

Lines or surface stains on the veneer may darken and change its color. There are simple ways to fix this problem, which can be mentioned by polishing or peeling the veneer. However, it is not recommended to polish the veneer at home. Therefore, it is better to visit a dentist to clean your teeth. Exfoliation of the tooth veneer will bring back its shine and beautiful color.

How to prevent the tooth coating from turning black?

If the dentist did not install dental veneers in a proper and standard way, here are some solutions to prevent the tooth veneer from turning black:

  • Before going to the dentist, check his treatment results.
  • Do not smoke.
  • Limit excessive alcohol consumption.
  • Do not use teeth cleaning products without consulting a dentist.
  • Follow the health and care tips.
  • See your dentist every four months.
  • Choose a healthy diet for yourself.

Examination of treatment results and opinions of clients in choosing a dentist

It is very important to choose a skilled and experienced dentist for dental crown installation. In this way, secondary complications can be prevented. It’s better to go to a dentist with a track record of good treatment results than to a dentist you know nothing about. One of the ways to choose a dentist is to check the opinions and records of the treatment center on the Internet. This will help you make more accurate choices.

Do not smoke

Smoking causes serious damage to your general health and oral health. If you don’t want your tooth enamel to turn black or lose its luster, you should quit smoking. Most of the complaints we receive about the darkening of dental veneers come from smokers.

Avoid excessive alcohol consumption

Alcohol consumption can also change the color of the tooth coating and create black lines on it. Limiting alcohol consumption can extend the life of your dental veneers. Avoid alcohols such as red wine to prevent stains on the enamel surface.

Do not use toothpaste and strong cleaners

Certain compounds used in dental products can damage tooth enamel. Whitening chemicals such as hydrogen peroxide, if used in excess, can cause tooth enamel to darken. Whitening products should not be used on dental veneers. Because dental veneers are very sensitive and can be easily damaged.

Follow the oral hygiene routine

A proper oral hygiene routine prevents dental problems. This hygiene routine helps the health of your teeth and prevents them from turning black. Therefore, stick to an oral hygiene routine to prevent damage.

See your dentist every four months

In addition to the oral hygiene routine you follow at home, try to visit your dentist every four months. This allows your dentist to monitor your oral health and see if your veneers are healthy enough. Before the problems escalate, the dentist can easily fix them.

Eat a healthy diet

A healthy lifestyle can increase your lifespan. Also, this method can increase your oral health. As long as you stay away from sweet foods and drinks. Eating a healthy diet will keep your teeth in good condition and prevent them from becoming discolored.

What is the reason for dental veneer leakage?

A leaky veneer means that the bonding is not done properly. This may happen due to the dentist’s lack of experience or neglect of dental problems. When a dental crown is not properly bonded, food can get into the interdental space and cause a leak. The best way to find the cause of the leak is to see an experienced dentist in Toronto.

Is it possible for the tooth under the cover to face severe decay?

Yes, severe tooth decay under a crown can occur due to a transient root canal, a cracked tooth, or gum disease. Dental crowns cannot protect your teeth from severe decay. If you do not take care of your oral hygiene, smoke, and drink alcohol, severe tooth decay can damage your teeth. The best way to address any type of damage is to see your dentist for regular checkups.

What to do if the dental veneer turns blue?

Dental veneers turn blue when bonding is not done correctly. Bonding materials or liquids can leak through the crown and cause damage to other teeth. These conditions require immediate dental intervention and should not be ignored. In severe cases, this problem may cause gum irritation and sensitivity. Therefore, we recommend that you do not wait until acute conditions develop and damage your oral health.
