Can my dentist improve my smile?
There are many techniques and options to treat teeth that are discolored, chipped, misshapen or missing. Your dentist can reshape your teeth, close spaces, restore worn or short teeth or alter their length. Common procedures include bleaching, bonding, crowns, veneers, and reshaping and contouring. These improvements are not always cosmetic. Many can improve oral problems, such as your bite.
Bleaching
Bleaching is a common and popular chemical process used to whiten teeth. Some people get their teeth bleached to make stains disappear, while others just want a whiter shade. Discoloration occurs in the enamel and can be caused by medications, coffee, tea and cigarettes. Discoloration also can be caused by your genetic make-up or simply getting older.
Bleaching can be performed by your dentist in the office or, under dental supervision, at home. Many patients prefer bleaching at home because it is more convenient. Treatment begins when your dentist creates a custom mouthpiece to ensure the correct amount of whitening solution - 10% to 20% carbamide peroxide - is used and that your teeth are properly exposed. Typically, whitening at home takes two or three weeks, depending on the desired shade you wish to achieve. Whitening in the office may call for 2-6 45-minute visits to your dentist's office.
Bonding
Bonding is tooth-colored material used to fill in gaps or change the color of teeth, requiring just a single office visit and lasts several years. Bonding is more susceptible to staining or chipping than other forms of restoration. When teeth are chipped or slightly decayed, bonded composite resins may be the material of choice. Bonding also is used as a tooth-colored filling for small cavities, and broken or chipped surfaces. Additionally, it can be used to close spaces between teeth or cover the entire outside surface of a tooth to change its color and shape.
Crowns, also known as caps, are used in cases where other procedures will not be effective. Crowns have the longest life expectancy of all cosmetic restorations, but are the most time consuming.
Veneers
Veneers are placed over the front teeth to change their color or shape. They are used on teeth with uneven surfaces or that are chipped, discolored, oddly shaped, unevenly spaced or crooked. Veneers are thin pieces of porcelain or plastic cemented over the front of your teeth.
Veneers are used to treat some of the same problems as bonding. This treatment is an alternative to crowns, which are more expensive. The procedure requires your dentist to take an impression of your tooth/teeth. Before the custom-made veneer is glued directly onto the tooth, your dentist will lightly buff the tooth to compensate for the added thickness of the veneer. Once the cement is between the veneer and your tooth, a light beam is used to harden it. Porcelain veneers require more than one visit because they are fabricated in a laboratory . Veneers have longer life expectancy and color stability than bonding.

Tetanus booster for adults
Tetanus does not result from the rusty nail or whatever created the wound. The danger lies in the bacteria Clostridium tetani that lives in the soil or manure on that nail or gardening tool. When these spores get into a wound—deep or shallow—they can produce a potent toxin. Also called lockjaw, tetanus seriously affects the central nervous system and can be fatal.
Onset of symptoms can occur anytime from three days to three weeks. Call your health care provider if you have an open wound, particularly if:
Adults should have a tetanus booster shot every 10 years, known as the Td vaccine. It is a "2-in-1" vaccine that protects against tetanus and diphtheria. It contains a slightly different dose of diphtheria vaccine than what you received as a child. It can be given to anyone older than 7 years and is injected, usually into the arm.
Instead of the standard Td booster every 10 years, adults between the ages of 19 and 65 should receive Tdap one time in their adulthood to boost the immune system for pertussis, as well as tetanus and diphtheria.
Diphtheria, a contagious bacterial infection created that causes severe inflammation of the throat and larynx and can also affect the whole body. Pertussis or “whooping cough” is a serious bacterial infection that afflicted children and infants before vaccines were available. Adults may be infected later in life as their immunities wane. Neither of these infections are related to tetanus, but both vaccines are compatible and convenient to use with the tetanus booster.
