Possible Difficulties

The aim of professional teeth whitening is to return the teeth their natural color. As a rule, teeth whitening does not snow-white, and only slightly brightens them. Stains on the teeth can occur due to various foods and beverages, such as coffee, tea, and wine. Smoking gives the teeth a yellowish tint. For many people, the teeth become darker as they age. Plaque and tartar Plaque - why it should be removed? , Illness and medications can also cause tooth discoloration Teeth Whitening - miracles are possible, but whether it is desirable? .

When deciding whether you need teeth whitening, it is important to think in advance about the desired result, and set realistic goals. The result is a professional tooth whitening is usually stored up to three years. The exact duration depends on the person's lifestyle, particularly against the above factors.

A professional tooth whitening may have undesirable side effects. Sometimes, after the procedure, the teeth become more sensitive to cold, but in the gums often appears white bloom. Most side effects disappear after a few days after bleaching. If they persist for two weeks or more, you should contact your doctor.

Active substances that are used for professional teeth whitening Teeth whitening - which option is right for you? They are oxygen peroxide or carbamide peroxide. They provide oxygen to the enamel of teeth so that the color becomes lighter. Professional teeth whitening is carried out in several stages, which in total takes three to four weeks. As a rule, for one session bleaching agent applied to the teeth for 30-60 minutes. Some types of professional whitening active substance is left on the teeth for up to eight hours. The results of the bleaching may be noticeable in a week, but it may be more harmful to tooth enamel.

Internal whitening

This is one form of professional teeth whitening. It applies only in those cases where the patient treated tooth roots, and as a result of the treatment have been replaced by the nerves and blood vessels. Each tooth drilled hole placed in a bleach and close the hole. Typically, the agent is removed after a week. To achieve makes hue whitening this technique can be combined with others.

Laser whitening

This procedure is applied on a teeth whitening agent, and then activate it with a laser. With such a whitening teeth may be five or six colors lighter. This is the most expensive form of teeth whitening.

Which teeth are difficult to bleaching

It has teeth that are difficult to bleach. It:

• teeth with enamel defects, since they can always be colored food dyes;
• teeth with a high degree of transparency;
• teeth, which for many years were subjected to not very intensive, but continuous dyeing, such as green tea;
• teeth after treatment of resorcinol or formalin, stained by amalgam fillings;
• teeth enamel which is in contact with the metal (eg, metal pins inside the crown);
• teeth, changing its color as a result of fluorosis Fluorosis - if too much fluoride   or treatment in childhood tetracycline, and were treated with the teeth, which removes the soft tissue (pulp); such teeth better than bleach, combining external bleaching with bleaching inside the crown.

So whether you want to whiten your teeth at all? If you are used to monitor their appearance, the bleach discolor the teeth, of course, necessary, but just right, considering all the "pros" and "cons" and the real professionals.

Bar prosthesis - the most rational design

With the destruction or removal of the tooth is required to restore its function using a prosthesis, such treatment is engaged in prosthodontist. Orthopaedic treatment of dental patients pursues preventive and therapeutic target, restores the shape and function of the oral cavity, prevents the further development of the disease. With the loss of teeth (caries More about caries - take care of your teeth until it's too late And various diseases of soft tissues surrounding the tooth, trauma, etc.) interferes with the structure of the dentition, which leads to disruption of mastication, and appearance of speech rights.

Thus there is a redistribution of loading on individual teeth if no top or bottom of the tooth, the tooth, with which it had come into contact, loses its load, while other teeth receive additional load. Teeth, close to the remote, start to move towards each other and gradually almost completely merge. Timely prosthesis may prevent such movement and remove the additional burden to the other teeth, warn that their premature failure.

Types of dentures

Dentures are removable and fixed. Which kind of prosthesis is indicated for this patient decides prosthodontist.

Fixed prosthesis - is the individual artificial teeth, bridges (artificial crowns are placed on two adjacent defective tooth, and between them is an artificial tooth) and cantilever prostheses (with a supporting part and an artificial tooth). This type of prosthesis permanently in the mouth of the patient.

Dentures - they can be laminar (used for large defects dentition) and clasp (arc).

How the clasp prostheses

Clasp dentures are the most rational design partial dentures. Clasp or arc prosthesis has a base (a plate of metal, repeating the exact topography of the teeth), artificial teeth, arch and its branches and clasps. Basis covers only the toothless areas, leaving a free sky and the part where there are natural teeth. Parts of the base, called a saddle, interconnected arc - clasp. The basis of partial denture is the metal frame (arc, clasps and other necessary tools that are out there are fixed).

Clasps are support-locking devices that secure the prosthesis to the remaining teeth. The device allows you to reduce the area of ​​the base and divide it into parts (saddle).

As shown in partial denture

Partial denture is used in the initial stages of the destruction of the dental arches when the remaining teeth are allowed to place the clasps, so that there was no danger of a rough functional teeth overload. Arc prosthesis allows you to distribute the load between the support chewing teeth and the mucous membrane of the underlying tissue.

Principles partial denture

The frame of the arc of the prosthesis must exactly match bridged space (box), consist of a minimum fine details, while maintaining rigidity. The teeth that serve as a support for the clasps is called the reference. When selecting abutment teeth into account their location, height and shape of the crowns, the state of periodontal tissues, etc. Errors in the selection abutments lead to their functional overload and premature failure.

Incorrectly made prostheses may have too much pressure on the tissue surrounding the teeth and cause them to atrophy (shrinking) injury. The material from which the prosthesis is made, can cause allergic reactions Allergic reactions: how to understand why you tickle in the throat   or have a toxic effect on the surrounding tissue.

Using the denture, the basis of which corresponds to the relief of bad prosthetic bed, not only leads to injury of the mucous membrane, but also to the loosening of the remaining teeth and other violations in the dentition.

What feelings may arise after the establishment of partial denture

After the establishment of partial denture it is perceived as a foreign body, there is increased salivation, some people have retching, loss of taste and temperature sensation, shortness of biting and chewing food, blurred speech. After a partial denture can also disrupt the pronunciation of certain sounds. Slowly (within a month), these phenomena are, it is the habit of the prosthesis. After getting used to the prosthesis it is removed during sleep Dreams: how to understand our dreams   and conduct regular sanitary processing. But sometimes, if these events are held for a long time, it requires correction of the prosthesis.

Try to heal and restore the teeth of time, then it can be done with the least loss to health and minimal costs.
