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 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.
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.
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.
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.
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.
Antibiotics are widely prescribed to control bacterial infections. Sometimes they are given before a medical or dental procedure, to prevent a possible infection from occurring; this practice is called "antibiotic prophylaxis." In the recent past, physicians and dentists advised that people with certain medical conditions - including a number of heart problems and several types of bone or joint replacements - should always take antibiotics before many routine dental procedures. Today, their advice may be different.
A growing body of evidence now indicates that far fewer patients need to take this preventive step than was previously thought. As a result, the guidelines for prescribing antibiotic prophylaxis have recently changed - and they may do so again in the future. Why are the recommendations changing - and what do you need to know about taking antibiotics before coming to the dental office?
The Risk of Infection
We all know that bacteria - both helpful and harmful types - thrive in many parts of the body, including the mouth. Whenever circumstances make it possible for these microorganisms to enter the bloodstream, there's a slight risk that a bacterial infection may develop. This could occur in many dental procedures - and it could also occur during routine activities like chewing, brushing and flossing. In most cases, the risk is so small that the chance of a having bad reaction to antibiotics (while rare) is far greater than the chance of developing an infection; therefore, antibiotics aren't routinely used.
Some people, however, need to take extra precautions before having dental procedures. If you have been treated for some types of heart disease, or have had certain orthopedic procedures (including total joint replacement), we may advise taking antibiotics to protect against even a remote chance of infection. Recommendations are made on an individual basis, taking into account your medical history and a clinician's healthcare experience.
Guidelines for Antibiotic Premedication
Prophylactic antibiotics might be recommended before dental procedures if you have one or more of the following heart conditions:
- A heart transplant
- Artificial heart valves
- A history of infective endocarditis
- Some types of congenital heart problems - particularly if they haven't been completely repaired, or if their treatment involves prosthetic material
If you have undergone a joint replacement procedure, prophylactic antibiotics might be recommended if you also have one or more of the following risk factors:
- A systemic inflammatory disease such as rheumatoid arthritis or lupus erythematosis
- A weakened immune system resulting from HIV, cancer, radiation or chemotherapy, or another cause
- Insulin-dependent (type I) diabetes or hemophilia
- A history of previous infection in a prosthetic joint
- Undernourishment or malnourishment
There are other circumstances where taking prophylactic antibiotics would be a prudent step; there are also a number of situations where these medications might have been recommended in the past, but aren't currently required in all cases. For example, the presence of a benign heart murmur, a pacemaker or defibrillator, and certain heart diseases or congenital defects don't automatically mean that antibiotic prophylaxis will be needed.
In recent years, reports of drug-resistant bacteria and harmful side effects from some medications have increased public awareness of the consequences of overusing antibiotics. Fortunately, new scientific research is helping healthcare professionals make better, evidence-based treatment decisions on antibiotic use. If you have questions about whether you should take antibiotics before dental procedure, don't hesitate to ask.
Premedication for Dental Treatment If you have had a total joint replacement in the past, you may be advised to take antibiotics before have dental work. That's because certain preexisting health conditions may make you more susceptible to infection during a dental procedure. Find out what the risk factors are... Read Article
