A gold crown is a kind of “cover” that is placed on a seriously damaged tooth that is unable to perform its functions. This “cap” helps a person chew food comfortably again without experiencing discomfort or pain. The prosthesis can be made either for one damaged tooth or in the form of a bridge that fills the empty space in place of several missing teeth.
Crowns are made from high-grade gold - 900 gold standard. It is this high-quality metal that is best suited for making a dental “cap”, because it does not oxidize from contact with moisture and is hypoallergenic. At the same time, gold is a fairly durable material that can withstand heavy loads when chewing hard food.
What it is
Gold crowns are “caps” made of dental gold 900 and placed on the teeth to restore chewing functions. They can be used to correct the defect of a single tooth, or to replace several missing teeth using a metal bridge.
Gold has been used in dentistry for centuries and this is not an accident. This metal does not cause negative reactions from the body, is not subject to oxidation under the influence of saliva, and does not cause allergic reactions. At the same time, it is quite durable and can withstand even significant chewing loads.
Use of gold in dentistry
There are two ways to make such crowns: stamped and cast. For stamped ones, special blanks are made. Cast products are cast from gold using wax casts. They do not require any adjustment during installation because they already have a certain size. Cast products are more expensive than stamped ones, but in this case the tooth has to be ground much harder.
Dental crowns from 850 to 900 gold are used. In order for the prosthesis to be stronger, it is made not from pure gold, but with the addition of silver and copper.
Advantages and disadvantages
Advantages of false teeth made of gold:
- High biocompatibility with tissues of the human body. Gold does not cause the development of allergic reactions, is not toxic and does not provoke discoloration of the gums and enamel of adjacent teeth.
- Under the influence of oxidizing agents, gold crowns do not corrode and do not oxidize in the mouth. Therefore, they do not change the taste of saliva and cannot cause the development of an unpleasant odor.
- The sufficient softness of the metal makes it possible to produce crowns that exactly match the tooth being prosthetized and fit tightly to the supporting dense tissues.
- Gold has a high strength coefficient, does not chip and can withstand constant intense loads, so it is ideal for prosthetics of chewing teeth.
- Long service life. With proper prosthetics and proper care, gold crowns can last up to 15 years or more.
- Gold teeth have the same abrasion coefficient as natural enamel, so such dentures do not cause damage to the hard tissues of antagonist teeth.
- The anti-inflammatory effect is a reliable prevention of caries of supporting teeth under crowns.
But, despite the large number of advantages, several disadvantages of gold teeth can be noted:
- The low aesthetics of gold structures makes them undesirable for dental prosthetics in the visible smile area.
- The need to prepare a tooth for a crown is due to the fact that it is necessary to remove part of the hard dental tissues to ensure a tight fit of the metal structure. In addition, the gold prosthesis has a certain thickness that must be turned.
- The cost of gold false teeth is quite high.
Is fashion coming back?
Golden teeth that sparkle in the mouth are no longer relevant - such a statement was an axiom until quite recently. But it is possible that smart prosthetics is approaching us. Goldtooth is the name of the development of Tashkent scientists. This is a kind of analogue of Bluetooth. But the carrier is not a computer, but a gold crown “stuffed” with high technology. If you have such a miracle in your mouth, then you can talk on your mobile phone without holding it in your hand, dictate letters for email, surf the Internet... Is it hard to believe? But until recently, mobile phones were something of a fantasy.
Under the influence of changing fashion, grillz - gold overlays for teeth - have become popular among show business stars. Now Rihanna, Madonna and Katy Perry are flashing their “precious” smiles. Of course, such removable options are decorative and worn at a party, but who knows, maybe gold will come back into fashion.
Manufacturing
Gold metal crowns are of the solid-cast type and are manufactured in several stages:
- After preparing the oral cavity and grinding the teeth, impressions are made of the dentition of the upper and lower jaw.
- In the laboratory, based on impressions, plaster models are made, which serve as a standard and an exact copy of the patient’s dental characteristics for the technician.
- In accordance with the plaster model, wax copies of future crowns are made, which are sent to the dentist’s office for fitting and adjustment.
- If the patient and doctor are satisfied with everything in the wax model, then the final gold crowns are cast on its basis, which are then ground and polished.

Possible problems after prosthetics
Even with high-quality work by doctors and patient compliance with all rules, side effects from prosthetics may occur. They are rare, but the main consequences include:
- Discomfort when eating food. After teeth restoration, it is recommended to refrain from consuming solid foods for 2-3 days: chips, crackers, apples, so that the jaw muscles have time to adapt to the changed chewing load.
- Increased sensitivity of the dentin of the restored unit. The situation occurs after the pulp is removed from the tooth before its preparation. The symptom does not indicate any complications and can be relieved with pastes for sensitive enamel.
Installation
The process of installing gold crusts takes several visits to the dentist’s office:
- At the first visit to the doctor’s office, the patient’s oral health is examined, caries is treated and, if necessary, old fillings are replaced. The dentist grinds the tooth on which the gold structure will be installed. In this case, dense dental tissues are ground down within 1 mm, when for metal-ceramic dentures this figure reaches 2 mm.
- After making impressions, the doctor makes a temporary overlay plastic prosthesis on site, which protects the tissues of the supporting tooth and performs an aesthetic function.
- At the second visit, the dentist tries on a wax model of the prosthesis for the patient, adjusting it and correcting any identified deficiencies.
- During the patient's third visit to the doctor, the final gold crown is tried on and fixed with temporary cement for up to three months. This is necessary in order to finally verify the correctness of manufacture and the comfort of the design.
- After 3 months, the crown is removed, cleaned of cement residues, and its effect on soft tissue is checked. If there are no contraindications, the gold prosthesis is fixed to permanent composite materials.

Removal
Sometimes situations arise when it is necessary to remove the crown.
This happens in the following cases:
- the occurrence of complications or inflammation in the oral cavity;
- replacing the crown if a crack, hole appears on it, or the structure as a whole is damaged;
- poor-quality preparation of the oral cavity before prosthetics (poorly sealed canals);
- occurrence of problems of the oral cavity of a physiological nature (bite distortion, aesthetic disturbances);
- when its expiration date has expired .
If the crown is severely damaged or has expired, it is sawed and removed.
When it is necessary to preserve the structure, the crown can be removed using :
- crown removers - special manual or automatic tools;
- forceps>;
- ultrasonic installation , which, acting on the connection of the structure, destroys the cement, after which the prosthesis is easily removed.
- pneumatic instruments , with which the orthopedist destroys the connective cement.
Life time
Gold crowns are considered one of the most durable dentures. If such structures are made correctly and are ideally suited for a person, as well as with proper care for them, their service life on average reaches 15 years. But there are often cases when such crowns do not need to be replaced or repaired even after 20-25 years.
Gold crowns are reliable and durable structures, but only a dentist can correctly assess the possibility of installing them for each patient. When choosing one or another method of prosthetics, you need to listen to the opinion of a specialist.
When gold crowns are the best solution
Patients at Aesculapius dentistry are prescribed the installation of similar structures in various cases. They will help if required:
- restoration of the shape of a damaged tooth;
- improved aesthetics;
- strengthening weak units;
- bite correction;
- restoration of chewing teeth;
- getting rid of parafunctional habits.
Sometimes experts do not recommend placing gold crowns. Designs are contraindicated for patients under 16 years of age, with periodontal problems, mental illness and pregnant women. It is better to check with a specialist for information about the possibility of installing crowns in a particular case.
Rehabilitation
During the rehabilitation process after crown installation, the patient may experience the following sensations:
- Minor discomfort and increased tooth sensitivity. Often this situation occurs during the first time after installation of the product and the cessation of anesthesia. Over time, the sensitivity will go away. Dentists recommend using a special toothpaste during this period to reduce sensitivity.
- The appearance of pain when biting. If you experience pain while eating, you should contact your dentist. The shape or position of the prosthesis may need to be adjusted.
- Taste of cement in the mouth. In such a situation, there is a possibility of it being washed out from under the crown. To avoid the development of infection, you must contact your dentist.

Rules of care
Many patients are interested in the issue of caring for gold crowns. No special skills are required to maintain them correctly. It is enough just to regularly carry out oral hygiene procedures.
Brushing your teeth should be done at least twice a day. In this case, it is better to use a brush with soft bristles, and the toothpaste should contain a minimum amount of abrasive particles.
In addition, it is recommended to use floss, which helps clean the space between the teeth. This procedure helps prevent deposits of tartar and plaque in the areas where the crown meets the gum and on the rest of the surface.
What to do if a crown with a pin falls out
In the age of modern technology, dentistry also does not stand still.
It is equally important to monitor your diet. Solid foods such as nuts and seeds should be excluded from the diet. Nail biting is not allowed. Grinding of teeth and strong clenching are also not allowed.
If there is a disorder such as bruxism, experts advise installing special devices during night sleep - mouthguards that will protect the teeth from unwanted mechanical influences.
It is also important not to forget to regularly, at least twice a year, undergo a preventive examination, during which the doctor will evaluate not only the condition of the installed crowns, but also the entire dentition.
Hygiene measures
No special conditions are required to maintain operation. Cleaning is carried out with a toothbrush with soft bristles, sweeping movements in the direction from the gums to the free edge. Plaque on the surface of the alloy practically does not accumulate due to the smoothness of the coating.
You should use floss or dental floss to remove food debris from the interdental spaces. For convenience, you can purchase an irrigator - a device that cleans with a thin stream of water.
Is it possible to remove
There are situations when early crown removal may be necessary. Indications for this action are as follows:
- the occurrence of inflammation in the oral cavity;
- formation of cracks, chips or complete damage to the surface of the product;
- lack of preliminary sanitation of the oral cavity, as a result of which carious lesions of the tooth developed;
- bite problems;
- expiration of the installed crown.
The product is removed in the dental office using special devices.
Reviews
Gold crowns are often used in dental practice due to their strength and reliability.
At the same time, in terms of aesthetic indicators, these products are inferior to metal-ceramic and zirconium analogues.
