You may have noticed, as you get older, that the enamel of your teeth is looking worn in certain areas. Sometimes tooth wear takes the form of a minor chipping or fracturing at the incisal (cutting) edges of the teeth, or a loss of tooth material from the area near the gum line. In more severe cases, worn teeth look quite a bit smaller than they used to. Why does this happen?

Some wear with age is natural. But too much wear can interfere with your bite, expose more sensitive inner parts of the tooth to decay, and give you a more aged appearance.

There are things you can control that affect wear:

Your habits: Clenching or grinding habits, also called “bruxism,” is a major cause of tooth wear. The motion of teeth sliding over each other with forces that are beyond what's normal for biting or chewing causes a mechanical removal of tooth enamel. This can happen during sleep or periods of high stress. In either case there are therapies available, such as a thin, professionally made mouthguard that prevents your teeth from coming into contact with each other. Holding foreign objects, such as nails and bobby pins, between your teeth can also cause wear.

Your diet: Tooth enamel can be eroded (dissolved away) by acidic beverages, such as sodas, sports drinks and juices. Frequent snacking on sugary foods encourages the growth of oral bacteria that produce acid as a byproduct — also leaving your teeth vulnerable to tooth decay. Your saliva can buffer the effects of the acid in your mouth in about half an hour; if you consume these types of foods and beverages continually, there won't be enough time for this to work.

We can restore the appearance and function of worn teeth in a variety of ways. Porcelain crowns and veneers, for example, can re-establish the normal thickness and length of teeth while improving their color and giving you a more youthful appearance.

Dental crowns are excellent tools that we use to restore functionality, color and/or beauty to teeth and your smile. And while many people may have heard of them, often times there are many questions surrounding the process, costs and their maintenance. This is why we have put together this list of some of the questions we are commonly asked on this subject. Our goal is to provide you with straightforward answers so that you have a clearer understanding of the treatment and are comfortable making the decision to go forward with these excellent tooth restorations should they ever be required.

What Is A Crown?

A dental crown is a tooth-shaped “cap” or cover that a dentist places over a tooth that is badly damaged from trauma or decay in order to restore its color, strength, size and functionality. They are also used for cosmetic reasons to improve discolored or misshapen teeth.

Why Can The Cost Of Crowns Vary?

The reason the cost of a crown can vary greatly, even from dentist to dentist is quite simple. The most beautiful crowns require the artistry and years of experience of a team of dental professionals; your dentist and the laboratory technicians that handcraft crowns. To meet higher expectations of some individuals requires more experience, artistry and skill. And great art just tends to cost more. A customized temporary crown may even be used as a preview to see what a final crown will look like. Another critical factor is the choice of materials used. For example, while all porcelain crowns are made from high-quality ceramic (glass) material, they are not equal. It is therefore more expensive in terms of time, skill and expertise to produce the most natural looking results.

How Long Will A Crown Last?

Most dentists expect a crown to last at least 7-10 years with normal wear and proper maintenance. However, depending on the materials used and location of the tooth, they can last upwards of 50 years or more. For example, a gold crown has the longest lifespan because gold is such a durable material that has little to no negative impact on surrounding teeth. On the other hand, porcelain produces a completely natural look but can cause wear to adjacent teeth.

What Materials Are Most Often Used For Crowns?

The three most common materials used to make crowns are as follows:

• Gold
• Porcelain-Fused-to Metal (PFM)
• All porcelain

We have noticed that there are two types of patients when it comes to enhancing a person's smile. One type, which we'll call the “Perfect Minded” patient, expects teeth that are completely regular in their arrangement and of maximum whiteness and brightness, often beyond the range of traditional guides for tooth color. They are looking for a perfect “Hollywood” smile. The other, the “Natural Minded” patient, is looking for a more natural look. This person expects a general sense of regularity and alignment of teeth with definite brightness, but not so much that the teeth are noticeable before and above other facial features. Which type are you?

The “Perfect Minded” Patient
While you expect maximum regularity and alignment of teeth along with maximum whiteness and brightness, the “perfect minded” patient requires a smile completely symmetrical (balanced from one side to the other). If we drew a vertical line down the center of your face (midline), it would fall directly between your front teeth and your smile would look just the same on each side of the line. You also expect your smile to be horizontally symmetric, so that it matches the curvature of your lower lip and the gum lines match from side to side.

The “Natural Minded” Patient
You are looking for a more subtle, natural look produced by including some minor irregularities in your look. Like the “Perfect Minded” individual, you still expect your teeth to be generally regular and well aligned but you also want to have some minor asymmetries (not matching) as you move farther back along your jaw to make your teeth look real. Your preference in tooth color is not a super shade of white, but for a tooth color that looks very natural for your facial skin and hair color.

There is no right or wrong here. What is important is to be sure to communicate your expectations to us before embarking on a program of smile redesign.

Time to tune up the brightness on your teeth? Here are six modern methods of whitening and brightening your smile.

• In-office “power” bleaching under the supervision of my staff and me is recommended if your teeth are badly stained, or if you are about to have veneers or crowns made. It's quick, safe, and effective. Gels containing high concentrations of bleach are applied to your teeth in our office, often with the enhancement by heat and light to make them act faster. Results show teeth becoming up to ten shades lighter in about an hour.
• “Take home” whitening solutions and trays are designed to fit your mouth and can also be provided by my office. The technique is easy to perform and is less expensive than in-office power whitening system, although it takes longer to see the same results. General recommendations are for 30 minute applications twice a day. You can usually see a change after two to four sessions. This requires patience, because it is important not to exceed recommended exposure in order to avoid damage to your teeth, gums, and the inside skin of your mouth. After two weeks of use, teeth can be expected to be about eight shades lighter.
• Whitening strips look like clear Band-Aids that are applied to the tooth surfaces. They should be worn twice a day for 30 minutes each time, for seven days. On average, they claim to lighten teeth more than three shades. They take about two weeks to work at 30 minutes per day.
• “Paint on” or “Brush on” whitening formulas are also available. These are gels that are painted onto the teeth every night at bedtime, for two weeks. Some claim that this line of home whitening can whiten teeth two to five shades. These gels may make your mouth feel goopy, but they are relatively inexpensive. Some gels come with a small brush to scrub them onto the teeth.
• Over-the-counter “mouth-tray” whiteners use mouth trays that are not designed for your particular mouth, so they may not fit well and may be messy or uncomfortable. They are filled with gel and worn 45 minutes a day for one week. On average, teeth become two shades whiter.
• Whitening gum is a relatively new product. It requires chewing two pieces for at least 20 minutes, four times a day, to see an effect.

If you've ever looked through a magazine and viewed the perfectly aligned white smiles of celebrities and models, you may be already familiar with the look of porcelain veneers. To achieve a picture-perfect smile, many Hollywood stars choose porcelain veneers (thin-layers of porcelain) that are bonded to the front of teeth allowing for the alteration of tooth position, shape, size and color. By fixing imperfections, as well as whitening them, veneers offer celebrities a perfect smile that, when maintained properly, can last for several decades.

Evaluation: If porcelain veneers sound appealing, our office can help you decide if you're a good candidate for them. We will ensure you have sufficient tooth structure, that your teeth are in more or less a normal position, and that symmetrical gum contours are present, allowing for proper “framing” of the teeth, necessary for a beautiful smile.

The Process: Once it's been determined that you're a good candidate for veneers, our office will begin a smile analysis using computer imaging to digitally replicate your smile and then fabricate a mock-up smile made of tooth-colored wax. We will work with you to determine the right color and shade for your veneers. You can choose the brightest, whitest “Hollywood smile” or opt for a more natural color and enhanced look.

Next Steps: After your initial appointment, it typically takes the laboratory one week to fabricate your porcelain veneers. The insertion of your veneers can be done with or without a local anesthetic. We will place the veneers on your teeth with a light-sensitive resin, which sets with the use of a white light, effectively bonding them to your teeth. While you may initially experience some tooth sensitivity to hot or cold, this will disappear after a few days. Maintaining your perfect smile requires simple brushing and flossing techniques and routine check ups.
