Dental veneers are a popular way to improve teeth with chips, stains, gaps or other defects. They're typically made of dental porcelain, ceramic-like materials prized for their ability to mimic the texture, color and translucency of natural teeth.
But dental porcelain doesn't come in one form—a dentist can utilize variations of it to better match a patient's need. For example, one patient may need a porcelain with added strength, while another may need one that provides better coverage of underlying discoloration.
The foundational materials for veneer porcelain are glass ceramics. Also used for crowns, glass ceramics have been the preferred choice of dentists for some time to achieve life-like results. In terms of veneers, dental technicians first mix the powdered form of the porcelain with water to create a paste. They then use the paste to build up the body of a veneer layer by layer.
But while the high degree of silica (glass) in this type of porcelain best resembles the translucence of natural teeth, early forms of it lacked strength. This changed in the 1990s when technicians began adding a material called leucite to the ceramic mixture that enhanced its strength and durability.
Today, you'll also find lithium disilicate used, which is twice as strong as leucite and is quite useful when creating thinner veneers. Both of these strength materials can be pressed and milled into shape, which helps achieve a more accurate fit. Along with the underlying glass ceramic, the result is a veneer that's both durable and incredibly life-like.
Although today's porcelain veneers are far superior in durability than earlier forms, they can be damaged when biting down on hard objects. To make sure your veneers last as long as possible, you should avoid biting down directly on hard-skinned fruit, or using your veneered teeth to crack nuts or crunch ice (or any other teeth, for that matter).
But with proper care, today's veneers have exceptional longevity. And, thanks to the superior dental materials that compose them, they'll look great for years.

You've just finished your daily brushing and flossing. How did you do? Swiping your tongue across your teeth can generally tell you: It's a good sign if it glides smoothly; but if it feels rough and gritty, you better take another run at it.
This "tongue test," however, only gives you a rough idea of how well you're removing plaque, that thin bacterial film on teeth most responsible for dental disease. Plaque, though, can be sneaky, "hiding" in the nooks and crannies on the biting surfaces of teeth, around the gum line and in between teeth.
So, how do you know if you're clearing out any plaque holdouts? An effective way is to use a plaque disclosing agent. This over-the-counter dental product consists of a swab, tablet or solution, which contains a dye that's reactive to plaque.
After brushing and flossing as usual, you apply the solution to your teeth for about 30 seconds. You then take a look in the mirror: Any remaining plaque will be stained a bright color that makes it stand out. There are also agents with two colors of dye, one that stains older plaque and one for newer plaque.
The plaque staining not only helps you see how well you've been brushing and flossing, it can also show you areas in need of improved hygiene. For example, if you notice a scalloped pattern around the gum line, that may mean your brush isn't getting into that area effectively. In this way, you can use a disclosing agent to fine-tune your hygiene.
Repeated use of a disclosing agent is safe, but just remember the dye color can be vivid. It does wear off in a few hours, though, so perhaps schedule it for a day off around the house. You should also avoid swallowing any solution or getting any of it on clothing.
The ultimate test, though, is a thorough dental cleaning with your dentist at least every six months. They can verify whether you've been fairly successful with your brushing and flossing, or if you have room for improvement. If you do use a disclosing agent, you can also discuss that with them in working out better strategies to protect your teeth from tooth decay and gum disease.

There are many things to be concerned about with your infant. Thumb sucking shouldn't be one of them—at least not yet. Practically universal among young children, the habit normally fades by age four with no real harm.
If it persists beyond that age, however, it can lead to a poor bite (malocclusion). Late thumb sucking may also have a connection with another problem—the inability of a child to transition from an infantile swallowing pattern to an adult pattern.
A baby while swallowing thrusts their tongue forward to help create a seal around a breast or bottle nipple during nursing. This normally changes about age 4, though, to a positioning of the tongue against the roof of the mouth when swallowing. But if they don't transition and continue to thrust the tongue forward, it can place undue pressure on the front teeth and cause them to develop too far forward.
The result may be an open bite, in which a gap exists between the upper and lower teeth even when the jaws are shut. An open bite can also happen with late thumb sucking, but instead of the tongue, their thumb presses against the teeth.
As to thumb-sucking, parents should encourage their child to stop the habit beginning around age 3, if they haven't already begun to do so. The best approach is to use some form of positive reinforcement such as praise or treats. The sooner the habit ceases after age 4, the lower their risk for developing an open bite.
You may also need to be alert to continued tongue thrusting while swallowing, which may still continue even after they no longer suck their thumb. In that case, your child may need orofacial myofunctional therapy (OMT), a series of exercises directed by a trained therapist to retrain the muscles involved with swallowing. This therapy could further help a child properly transition to an adult swallowing pattern.
Open bites can be corrected orthodontically later in life. But by being alert to your child's oral habits, as well as the way they're swallowing, you and your dentist may be able to intervene and eliminate or at least lessen the development of this type of problem bite.
