Porcelain dental crowns grace you with beautifully radiant teeth. However, behind that brilliance hides the concern about the foul odor which may appear after the crowning. In fact, whether you will get bad breath from dental crowns or not largely depends on many factors, including crowning techniques, materials, and oral hygiene, etc.

Causes of bad breath after porcelain dental crowns

bad breath after dental crowning

Improper crowning techniques may lead to an undesired appearance of the teeth and bad breath. In many cases, failure to practice good oral hygiene after getting porcelain crowns may worsen preexisting bad breath.

  • Improper crowning techniques: If during the process of restoration, your dentist makes a mistake in calculating the ratio, he is likely to create a space between the crown and the tooth. When the crown isn’t placed securely on the tooth, either too loosely or at the wrong angle, foods may get stuck in between. Over time, you will develop bad breath which may interfere with your daily life quality.
  • Low-quality materials: If the materials used to make porcelain crowns, particularly porcelain-fused-to-metal crowns, are low-quality, they will be affected after a period of time. Under the impact of oral acids and bacteria, these materials will oxidize and cause a foul odor.
  • Bad oral hygiene: If you don’t practice good oral hygiene frequently, foods will get stuck in the gaps between two teeth, particularly in the area with porcelain crowns, resulting in bad breath.

In addition, you should also keep in mind that your bad breath may be a preexisting condition. Getting dental crowns helps you realize you have bad breath, not causing it. In some cases, the cause of bad breath is actually an oral infection or a disease of the stomach.

Treatment for bad breath after getting porcelain crowns

chew gum to clean teeth

To get rid of bad breath after crowning, the most basic step to do is find the exact reason. Here are some solutions for each problem:

1. Quality of porcelain crown:

Metal porcelain teeth are completely covered with porcelain inside, covered with 1 layer of metal. Metal porcelain teeth are low cost but easy to cause bad reactions for you because the metal part after many years will oxidize, causing the roots to have black and chipped borders, in the long term, the teeth will be deeply decayed and bad breath will happen. You will have to replace it with a different type of porcelain material that is more compatible with the body such as all-porcelain teeth, titanium porcelain teeth,.

Titanium porcelain crown has an inner frame made of titanium alloy and the outer part is made entirely of porcelain. Titanium is a safe material for the body and does not cause any reaction. However, after many years of using titanium porcelain crown, the gums will have dark stains, you should keep your teeth clean and replace them to avoid tooth decay, causing bad breath.

If you care about aesthetics, you should choose all-porcelain teeth because all-porcelain teeth have the same natural color as real teeth, have good strength, high durability, and ensure oral health and safety.

2. Due to technical fault:

The process of dental porcelain crowning is very important. If unfortunately your dental cavity is exposed, making small holes, this is the opportunity for bacterial plaque to invade causing bad breath and tooth decay. In this case, the dentist will remove and reattach the crown so that it fits tightly. In more severe cases, the dentist will have to retake the tooth impression and make a new crown.

3. Due to oral diseases:

To fully treat oral diseases, dentists will have to remove crowns. Remember to practice good oral hygiene to prevent bad breath after crowning. Here are some tips you may use to manage this condition:

  • Drink plenty of water: Water washes away food particles and bacteria stuck in the gaps.
  • Use chewing gums: Sugar-free chewing gums or peppermint candies with xylitol may promote your saliva production, serving as a natural way to cleanse the oral cavity.
  • Drink lemonade: Lemons are high in acids, making them good at getting rid of bad breath. You may mix lemon juice with honey to make lemonade or you can make a daily mouthwash with lemon juice and salt to keep your breath fresh.
  • Eat less food with strong smells: Consumption of foods with strong smells such as onions, garlic, coffee, tobacco, alcohol, etc. should be limited as much as possible.
  • Oral checkup: If home remedies fail to help you get rid of bad breath, you should visit your dentist so they may take a look at your crowns. If there’s a problem, your dentist will adjust your crowns or make you new ones to improve the drawbacks of previous crowning techniques.
