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.
With proper care, your teeth can last a lifetime. But some amount of wear as we age is normal. By “wear,” we mean loss of tooth structure. Wear starts with loss of the hard, translucent enamel that forms the outer covering of teeth, and might, in more serious cases, progress to the softer inner tooth structure known as dentin.
Enamel is actually the human body's hardest substance. It is highly mineralized and non-living, in contrast to bone and dentin which are living tissues. Enamel is highly resistant to wear and chemical attack, as it would have to be given what your teeth do every day: bite, chew, and come in contact with acidic foods and drinks.
Still, it is possible for tooth enamel to wear down for various reasons. Your body has ways of compensating for minor wear. But when tooth wear becomes more significant, intervention may be necessary to keep your bite functioning properly and protect your teeth.
Types of Tooth Wear
Tooth wear can result from one or more of these processes:
Abrasion: This is caused by the interaction of teeth and other materials rubbing or scraping against them. The most common source of abrasion is traumatic toothbrushing, meaning that you are using a toothbrush that's too hard or applying too much force when you brush. This can affect the root surfaces of your teeth just below the gum line or the enamel above the gum line. Other causes of abrasion can include improper use of toothpicks and dental floss. Some dental appliances such as partial dentures or retainers that are frequently taken in and out of the mouth can also abrade teeth. Abrasion can also result from a diet loaded with abrasive foods like sun flower seeds and nuts or habits such as nail-biting and pen-chewing.
Attrition: This is an effect of tooth-to-tooth contact, which happens many times throughout the day as your teeth bite and chew food. Biting and chewing normally generate forces between 13 - 23 pounds. Yet people who have clenching and grinding habits (of which they might not even be aware) can subject their teeth to forces up to 10 times that. This can damage teeth.
Erosion: When your teeth come in contact with acidic substances in your diet, the acid can actually erode (dissolve) the enamel on your teeth. Culprits of this kind of tooth wear often include sodas, sports drinks and so-called energy drinks. Certain fruit juices are also acidic. Confining these drinks to mealtimes and swishing water in your mouth after drinking them can help prevent this erosion.
Abfraction: This refers specifically to the loss of tooth enamel at the necks of the teeth (the thinner part right at the gum line). While this type of wear is not clearly understood and the cause is debated in dentistry, loss of tooth structure at the neck of teeth does happen. It is believed to be caused by tooth flexion from biting forces. Abrasion and erosion can contribute to this problem.
Treating Worn Teeth
In order to treat your worn teeth, the cause of the wear must be determined during a simple oral examination at the dental office. Once the cause has been identified, the stresses on your teeth can be reduced if need be. For example, you may need instruction on gentle, effective tooth brushing techniques; or some changes to your diet. If you have a clenching or grinding habit, a mouthguard can be custom-made for you that will protect your teeth during sleep or periods of high stress.
Lost tooth structure sometimes needs to be replaced so your bite functions properly and your teeth look great once again. Depending on the situation, this can be done with bonding, veneers, or crowns. Fortunately, modern dentistry can restore the normal shape, appearance and function of worn teeth — beautifully and successfully!
How & Why Teeth Wear Are teeth supposed to last for a lifetime? And are humans designed to live for up to a hundred years?
