Implants

Dental implants are a popular and effective way to replace missing teeth and are designed to blend in with your other teeth. They are an excellent long-term option for restoring your smile. In fact, the development and use of implants is one of the biggest advances in dentistry in the past 40 years. Dental implants are made up of titanium and other materials that are compatible with the human body. They are posts that are surgically placed in the upper or lower jaw, where they function as a sturdy anchor for replacement teeth.

Veneers

Veneers are thin, custom-made shells crafted of tooth-colored materials designed to cover the front side of teeth. They are an option for correcting stained, chipped, decayed or crooked teeth. Veneers are made by a dental technician, usually in a dental lab, working from a model provided by your dentist. Placing veneers is usually an irreversible process, because it's necessary to remove a small amount of enamel from your tooth to accommodate the shell. Your dentist may recommend that you avoid some foods and beverages that may stain or discolor your veneers such as coffee, tea or red wine. Sometimes a veneer might chip or fracture. But for many people the results are more than worth it.

Crowns

A crown can help strengthen a tooth with a large filling when there isn’t enough tooth remaining to hold the filling. Crowns can also be used to attach bridges, protect a weak tooth from breaking or restore one that’s already broken. A crown is a good way to cover teeth that are discolored or badly shaped. It’s also used to cover a dental implant.

Diastema

A diastema is an area of extra space between two or more teeth. The two front teeth of the upper jaw area is where diastema is most frequently seen. Many children experience diastema as primary teeth fall out, though in most cases these spaces close when the permanent teeth erupt.

Diastemas may also be caused by a tooth size discrepancy, missing teeth or an oversized labial frenum, the tissue that extends from the inside of the lip to the gum tissue where the upper two front teeth are located. Secondary reasons involve oral alignment issues such as an overjet or protrusion of the teeth.

Whitening

Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.

Does Whitening Work on All Teeth?

No, which is why it’s important to talk to your dentist before deciding to whiten your teeth, as whiteners may not correct all types of discoloration. For example, yellow teeth will probably bleach well, brown teeth may not respond as well and teeth with gray tones may not bleach at all. Whitening will not work on veneers, crowns or fillings. It also won’t be effective if your tooth discoloration is caused by medications or a tooth injury.

Root Canal

If you have a severely damaged, decaying tooth or a serious tooth infection (abscess), your dentist may recommend a root canal treatment. Root canals are used to repair and save your tooth instead of removing it.

 

 

 

 

 

Child sucking thumb.

Is there any image that illustrates the comforts of babyhood better than a sleepy infant sucking his or her thumb? Ultrasound pictures have shown, to the joy of many prospective parents, that this behavior can even occur in the womb. The thumb- or finger-sucking habit seems to relax and comfort toddlers too, and it's perfectly natural. But as a child grows, there comes a point where this habit isn't just socially awkward — it may also be harmful to his or her oral health.

In most children, thumb sucking stops on its own between the ages of two and four years. But if the practice persists after the primary (baby) teeth have erupted, it can drastically change the growth patterns of the jaw, and cause significant misalignment of the teeth. It may be hard to believe that such a benign habit can actually move teeth and bone — but there are a number of reasons why this occurs.

Children's jaws, rich in blood supply and growing rapidly, are relatively soft and flexible — especially in kids under the age of 8. So it really isn't hard for the constant pressure of a thumb or finger to deform the soft bone around the upper and lower front teeth. Children who are particularly vigorous thumb suckers are even more likely to change the growth patterns of the teeth and jaws.

If the thumb sucking habit persists, it can result in the upper front teeth flaring out and the lower ones moving back and inward. It can also hold back the growth of the lower jaw, while causing the upper jaw to be thrust forward. This can result in misalignment of the teeth, an anterior open bite (where the front teeth fail to close together), collapse of the upper jaw causing crossbite, or other problems. That's why it is important to stop the behavior at an appropriate time, before damage occurs.

Controlling Thumb or Finger Sucking

Like many potentially harmful behavior patterns, thumb sucking can be a difficult habit to break. Through the years, parents have tried a variety of home remedies, such as having the child wear gloves, coating the digits with a bitter-tasting substance — and even reasoning with their toddlers. Sometimes it works — but in other cases, the allure of thumb sucking proves very difficult to control.

Fixed palatal crib.

If your child has a thumb or finger sucking habit that has persisted past the age of 3, and you've been unable to tame it, then it may be time for you to visit the dental office for a consultation. A “habit appliance” such as a fixed palatal crib or a removable device may be recommended for your child. This crib isn't for sleeping — it's a small metal appliance worn inside the mouth, attached to the upper teeth.

How does it work? The semicircular wires of a palatal crib keep the thumb or finger from touching the gums behind the front teeth. Simply preventing this contact seems to take all the enjoyment away from the thumb sucking habit — and without that pleasurable feedback, a child has no reason to continue the behavior. In fact, the device is often successful the first day it's worn.

Getting and Using a Habit Appliance

If your child could benefit from a habit appliance, the first step is to get a thorough examination, which may include taking x-rays, photographs and dental impressions. If it's recommended, a crib will then be custom-fabricated to fit your child's mouth, and placed at a subsequent appointment. Afterwards, your child will be periodically monitored until the appliance is removed — typically, a period of months.

Although wearing the crib isn't painful, your child may experience some soreness in the upper back teeth for a few hours after it's first installed. He or she may also have a little trouble falling asleep for a day or two afterward. Plenty of extra attention and TLC are usually all that's needed to make everything all right. While the appliance is being worn, it's best to avoid chewing gum and eating hard, sticky food that might cause it to come loose.

A Word About Tongue Thrusting

Like thumb sucking, tongue thrusting is a normal behavioral pattern in young children. It's actually part of the natural infantile swallowing pattern, which will normally change on its own — by the age of six, in most children. If the pattern doesn't change, however, it can lead to problems similar to those caused by thumb sucking: namely, problems with tooth alignment and skeletal development. Fortunately, this problem can be successfully treated with a habit appliance that's very similar to a fixed palatal crib.

How Thumb Sucking Affects The Bite Thumb sucking can actually block the front teeth from erupting fully and can also push the teeth forward — sometimes more on the side where the thumb rested. How far out of position the teeth end up will depend on the number of hours per day the thumb was in the child's mouth and how much pressure was applied. When the pressure exerted by the thumb in the mouth is particularly strong and occurs over a long period of time, the forces can potentially influence growth of the jaws... Read Article
