Recently, a number of new filling materials that mimic tooth color have come into popular use and, so far, have proven more durable than past versions. Even so, the traditional metal-based dental amalgam remains a viable choice, especially for less visible back teeth and their higher biting forces.

Used for more than a century, dental amalgam is a metal alloy composed of silver, mercury, tin and copper. The mixture is carefully proportioned so that potentially hazardous mercury is kept to a minimum and bonded with the other metals. Amalgam in its initial form is quite pliable so that it can be molded into the tooth structure under repair. Afterward it sets hard to form a durable filling that can withstand the daily force generated when we bite and chew food.

Besides durability, dental amalgam rarely causes an allergic reaction in a patient, and it’s easy for trained dentists to apply. On the downside, however, it can cause temporary temperature sensitivity in the tooth just after filling, and the tooth itself may require some removal of healthy structure to help keep the filling in place. And from an aesthetic point of view, its metallic appearance is considered unattractive especially for front teeth.

The presence of mercury in amalgam has also raised concerns over the years. “Free” mercury — atoms that escape through vapor emitted by the metal — can enter the bloodstream and potentially harm the nervous system. But after extensive study and research, U.S. and international health bodies including the American Dental Association have concluded any free mercury released during chewing is extremely low and well below any harmful levels. These studies have also found no ill effects in either children or adults with dental amalgam fillings.

Deciding on the type of filling material to use — dental amalgam or a newer composite resin, resin ionomer or glass ionomer — depends on a number of factors including the location of the teeth to be filled, the extent of decay and your personal preferences. Taking these into account, we’ll be happy to discuss which type of filling will suit you best for repairing decayed teeth.

Straightening your teeth doesn't have to involve wearing ugly metal braces. When you choose Invisalign treatment, no one may even realize that you have braces. Matthew Karls, DDS, and Stanley Karls, DDS, of Karls Family Dentistry in Waunakee, explain how Invisalign can help you improve their smiles.Invisalign

What is Invisalign?

Traditional braces use wires connected to brackets to gradually move teeth into the proper alignment. Brackets are cemented on your teeth, where they remain during the entire process. The Invisalign system accomplishes the same objective with a series of clear, plastic, removable aligners. The custom-made aligners are much more comfortable than metal braces and are a good choice if you prefer a more natural-looking orthodontia option.

What flaws can Invisalign correct?

Invisalign may not be appropriate for severe alignment or bite issues, but it is very effective in improving the following conditions:

  • Crowding
  • Gaps
  • Open bites
  • Overbites
  • Underbites
  • Crossbites

How often will I change aligners?

Aligners are generally changed after about two weeks. You'll see your dentist about every six months to make sure that you're making good progress.

How long do I have to wear Invisalign aligners?

If you're an adult, you may only have to wear the aligners for about a year. Teenagers generally wear Invisalign aligners for the same amount of time they would wear traditional braces. The aligners are usually worn for approximately 20 to 22 hours per day.

What can't I eat?

There's a long list of foods you can't eat if you wear metal braces, but Invisalign wearers can wear anything they want. Since you remove the aligners to eat, no foods are off-limits.

If you live in the Waunakee area and think Invisalign offers the clear solution to your problems, call Drs. Matthew and Stanley Karls at (608) 849-4100. Thanks to Invisalign, you don't have to be self-conscious about your smile any longer.

When the multi-platinum recording artist, songwriter and TV personality Jason Derulo was recently asked about his ideal woman, his answer covered a remarkably broad spectrum. "There’s no specific thing," he said, "so I think it’s unfair to say what my ‘type’ is." But it turns out that there is one thing the So You Think You Can Dance judge considers essential: A beautiful smile.

"I’m not into messy teeth," Derulo said. "If the grill has spaces and different colors, it’s not my vibe."

As it turns out, he may be on to something: A number of surveys have indicated that a bright, healthy smile is often the first thing people notice when meeting someone new. Yet many are reluctant to open up that big grin because they aren’t satisfied with the way their teeth look. If you’re one of them, consider this: Modern cosmetic dentistry offers a variety of ways to improve your smile — and it may be easier and more affordable than you think.

For example, if your smile isn’t as bright as you would like it to be, teeth whitening is an effective and economical way to lighten it up. If you opt for in-office treatments, you can expect a lightening effect of up to 10 shades in a single one-hour treatment! Or, you can achieve the same effect in a week or two with a take-home kit we can custom-make for you. Either way, you’ll be safe and comfortable being treated under the supervision of a dental professional — and the results can be expected to last for up to two years, or perhaps more.

If your teeth have minor spacing irregularities, small chips or cracks, it may be possible to repair them in a single office visit via cosmetic bonding. In this process, a liquid composite resin is applied to the teeth and cured (hardened) with a special light. This high-tech material, which comes in colors to match your teeth, can be built up in layers and shaped with dental instruments to create a pleasing, natural effect.

If your smile needs more than just a touch-up, dental veneers may be the answer. These wafer-thin coverings, placed right on top of your natural teeth, can be made in a variety of shapes and colors — from a natural pearly luster to a brilliant "Hollywood white." Custom-made veneers typically involve the removal of a few millimeters of tooth enamel, making them a permanent — and irreversible — treatment. However, by making teeth look more even, closing up spaces and providing dazzling whiteness, veneers just might give you the smile you’ve always wanted.
