Porcelain crowns are a popular dental cosmetic solution, helping to quickly improve smiles. However, if the instructions are wrong or performed incorrectly, this method can cause many complications. Porcelain teeth are not inherently bad, the problem lies in how it is done. The following article will clearly analyze the benefits, risks and things to keep in mind when getting porcelain crowns.

The concept of porcelain crowns

Porcelain crowns(also known as porcelain crowns, porcelain crowns) is a popular cosmetic tooth restoration method, helping to overcome many defects in shape, color and function of teeth. By using a "crown" made from high-quality ceramic material, the doctor will cover the entire crown of the real tooth that has been ground down, creating a strong and natural cover.

Outstanding advantages of porcelain crowns:

  • Outstanding aesthetic improvement:Ceramic teeth have the same color, clarity and shape as teeth Real teeth, helping to cover up defects such as yellow teeth, antibiotic stains, chipping,...

  • Restoring chewing function:Porcelain teeth have high hardness, good load-bearing capacity, helping you eat and chew comfortably.

  • Protect real teeth:For large cavities, teeth that have had root canal treatment, porcelain crowns act as a protective layer of armor, preventing bacterial attacks and limiting the risk of disease recurrence.

  • Degree High durability:The lifespan of porcelain teeth can last from 10-20 years, even longer if properly cared for and quality porcelain is chosen.

  • Good biocompatibility:Current all-ceramic teeth are made from benign materials, do not irritate the gums and soft tissues in the oral cavity, and are safe for health.

Because of these outstanding advantages,porcelain crownshas become the top choice for those who want to have a perfect smile and better oral health. However, if you do not research carefully and make the right choice, you can easily make serious mistakes.

Mistakes when getting porcelain crowns

1. Choosing a less reputable dentist

This is the most serious mistake, determining up to 80% of the success of porcelain crowns. An unreliable dentistry often lacks the following factors:

  • Lack of good, experienced doctors:Doctors are the key factor. An inexperienced doctor can grind teeth too much, at the wrong ratio, causing damage to the pulp, or not fitting the porcelain teeth properly, creating gaps for bacteria to attack.
  • Lack of modern equipment:Modern technology and machinery such as digital X-ray machines, CAD/CAM machines (computerized design and manufacturing of porcelain teeth) help diagnose accurately, grind teeth with proper technique, and create porcelain teeth with high precision, tightly hugging the pulp. teeth.
  • Porcelain materials of unknown origin and poor quality:Floating porcelain teeth, without certification of origin or source, may contain toxic impurities, cause gum irritation, bad breath, or quickly degrade and break.
  • Non-medical standard process:Porcelain tooth crown process requires strict compliance with aseptic steps, examination, root grinding, impression taking, tooth testing, and fixation. Unreputable dentists often skip or do these steps poorly, increasing the risk of infection and complications later.

The consequence isPorcelain teeth are crumpled, canalized, have exposed gums, gingivitis, bad breath, pulpitis, and even lose real teeth. Money is lost, it costs money and time to fix it.

2. Only care about cheap price but ignore quality

The mentality of being cheap is a big trap when choosing dental services. The price ofporcelain crownsdepends on many factors such as the type of porcelain, technology, doctor's skills, warranty policy...

  • Cheap porcelain teeth:Usually metal porcelain teeth or porcelain of unknown origin. Metal-ceramic teeth after a period of use are easily oxidized, causing blackening of the gum line, loss of aesthetics and can cause irritation. Poor quality ceramics are not durable, break easily, chip, and do not ensure chewing function.
  • Low service costs:To reduce costs, less reputable dentists often cut costs on materials and equipment, or hire low-skilled doctors. This directly affects the quality and safety of porcelain crowns.

3. Don't research carefully about the types of porcelain teeth

The market today has many types of porcelain teeth with different advantages and disadvantages and prices. Not researching carefully can cause you to choose a type of porcelain that is not suitable for your needs and dental condition.

  • Metal porcelain teeth:Has a frame made of metal alloy (Cr-Co, Ni-Cr, Titanium) and ceramic coating on the outside. The advantage is low cost, but the disadvantage is that it easily oxidizes in the oral cavity environment, causing blackening of the gum line after a period of use, which is unnatural when light shines on it.
  • All-ceramic teeth:Crafted entirely from monolithic ceramic materials (Zirconia, Cercon, Emax, Lava Plus...). Outstanding aesthetic advantages (color, natural clarity like real teeth, no black gum line), high durability, good load-bearing, excellent biocompatibility. However, the cost will be higher than metal porcelain teeth.

Choosing the wrong type of porcelain can cause you to not achieve the desired aesthetic effect, or encounter problems with durability and biocompatibility.

4. Not thoroughly treating dental diseases before getting porcelain veneers

BeforePorcelain dental crowns, it is extremely important to examine and completely treat diseases such as tooth decay, pulpitis, gingivitis, and periodontitis.

  • Tooth decay, pulpitis:If a tooth decay is not thoroughly treated, bacteria will continue to grow under the porcelain layer, causing pulpitis, abscesses, severe pain, and even requiring the tooth to be removed.
  • Gingivitis, periodontitis:Gum and periodontal diseases, if not controlled, will cause the gums to swell and bleed, allowing bacteria to penetrate inside, causing gum recession, exposed porcelain roots, loss of aesthetics and can lead to tooth loss.

5. Not taking care of your teeth properly after getting porcelain crowns

Many people mistakenly believe that porcelain teeth do not need to be cared for as carefully as real teeth. But that is a serious mistake.

  • Improper oral hygiene:Not brushing your teeth twice a day, not using dental floss or water flosser to clean between teeth and plaque, creating conditions for bacteria to grow, causing real cavities inside the ceramic crown (if there is any), gingivitis, bad breath.
  • Improper diet:Eating too much hard, chewy, suddenly hot, cold food, or foods that easily stain (coffee). coffee, tea, red wine) can reduce the lifespan of porcelain teeth, cause chipping, or discoloration of porcelain.
  • No regular follow-up examinations:Follow-up examinations every 6 months help the doctor check the condition of porcelain teeth and gums, detect problems early and handle them promptly.

6. Grinding teeth too much or not using the correct technique

Tooth grinding technique is an extremely important step in theporcelain crownsprocess. Mistakes in this step can have serious consequences:

  • Grinding teeth too much:Causes irreversible damage to the tooth pulp, leading to pulp inflammation, pulp necrosis, requiring root canal treatment, even tooth extraction. Teeth that are ground too much also weaken the real tooth structure.
  • Teeth grinding at the wrong ratio:If not ground enough, the porcelain crown will be thick and rough, causing discomfort when chewing and affecting the bite. If grinding unevenly, the porcelain crown will not fit tightly, creating gaps for bacteria.
  • Do not grind the finishing line:This prevents the porcelain crown from hugging the gum line, creating gaps that cause food retention, gingivitis, and bad breath.

Consequencescausing pain, prolonged sensitivity, pulpitis, bad breath, receding gums, exposed tooth roots, and eventually having to remove porcelain teeth for treatment.

7. The porcelain crown does not fit tightly and the edges are exposed

After grinding and processing, the porcelain crown will be permanently attached to the real tooth. If this process is not accurate, the porcelain teeth will not fit tightly.

  • Porcelain teeth do not fit tightly:Creates a gap between the porcelain tooth and the real tooth base. Food and bacteria can easily get stuck and accumulate in this gap, causing secondary cavities (true internal cavities), gingivitis, bad breath.
  • Open gum line:In addition to causing food retention, exposed gum line also seriously affects aesthetics, especially in the front teeth area.

When to and when not to Should I get porcelain crowns?

Need to improve the aesthetics of tooth color

Teeth that are stained with Tetracycline, severe Fluorosis, or yellow that cannot be whitened by conventional methods. Porcelain teeth will help you have the bright white, even-colored teeth you desire.

In case of Tetracycline-stained teeth, porcelain crowns are needed to improve the color of the teeth

 

Need to improve tooth shape

  • Chiped or broken teeth: Due to accident, impact or chewing. Porcelain teeth will help restore the original shape of the teeth and protect the remaining real teeth.

  • Teeth that are irregularly shaped, too small, or too large: Porcelain crowns can adjust the size and shape of teeth to create harmony for both the teeth and the overall face.

  • Slightly spaced teeth, with small gaps: Porcelain crowns can help close gaps, creating seamlessness for the teeth. (Note: With teeth that are widely spaced or have large misalignments, braces are still the top priority).

Teeth that have undergone root canal treatment

 Teeth that have undergone root canal treatment often become brittle, fragile and discolored. Porcelain crowns not only restore shape and color but also help protect real teeth from the force of chewing, prolonging the life of the tooth.

Teeth with worn enamel due to age or bad habits

Porcelain crowns can protect teeth from continued wear and restore chewing function.

Porcelain bridge or dental implant

In case of tooth loss, porcelain bridge or porcelain crown on Implant is the optimal solution to restore lost teeth and restore them. chewing function and aesthetics.

2. Cases where porcelain crowns should not be used

Protruding teeth, underbite (reverse bite), severely crooked teeth

Ceramic crowns cannot completely solve the problems of malocclusion or serious tooth misalignment. Trying to get porcelain crowns will make your teeth look thicker, won't improve overall aesthetics, and can even cause problems with chewing and the temporomandibular joint.

Real teeth are too weak, loose, or have severe periodontitis

If the original tooth is not strong enough to serve as an abutment, the porcelain crown will not be sustainable and may make the dental condition worse. Periodontitis needs to be treated completely before considering any cosmetic procedure.

Suffering from uncontrolled systemic diseases

Certain medical conditions such as uncontrolled diabetes, cardiovascular disease, or being on medications that affect blood clotting can affect the healing process or increase the risk of complications. You should consult a general practitioner before doing this.

Poor oral hygiene

If you have poor oral hygiene habits, porcelain crowns will not help and can easily lead to tooth decay under the porcelain crown and gingivitis. You need to commit to maintaining thorough oral hygiene before and after porcelain crowns.

Have a habit of heavy teeth grinding

Teeth grinding at night can put a lot of pressure on porcelain teeth, leading to chipping and cracking. If you have this habit, you need to be treated or use an anti-bruxism tray before getting porcelain veneers.
