I'm 29, Am I too old for braces?

Great question, and you are absolutely not "too old" for braces! At Yang Orthodontics, nobody is “too old” for braces! In fact, we read a fascinating statistic recently: adults getting braces has actually jumped 24 percent since 1996! Also, one of every five patients in orthodontic treatment nowadays is over the age of 21. Of course, braces help make your teeth stay strong, healthy and become perfectly-aligned. But we’d like you to know orthodontic treatment with Dr. Stephen Yang can be successful at any age, and adults especially appreciate the benefits of a beautiful smile.
In fact, we are proud to offer an adult-friendly option for straightening teeth called Invisalign, which uses a series of invisible, removable and comfortable aligners that no one can tell you're wearing. So, you can smile more during treatment as well as after.
If you’ve been thinking about getting that perfect smile, we would love to have you visit for a consultation at our Redwood City, CA office. Please give us a call at (650) 366-5758 to set one up and have a wonderful rest of the week!

What is the right age to bring a child for an orthodontic evaluation?

Great question! Many parents ask us that question, actually. Many parents in Redwood City, CA  assume they must wait until their child has all of his or her permanent teeth to visit Dr. Stephen Yang for a complimentary consultation, only to discover treatment would have been much easier if started earlier. Did you know the American Association of Orthodontists recommends that every child have an orthodontic check-up no later than age seven?

Yes – seven.

At that point, enough permanent teeth have arrived for Dr. Yang to make a determination about whether any problems are present. Also, by age seven, the first molars have come in, providing an opportunity for the Doctor to check for malocclusion, or what we call “bad bite.” Also, the incisors have begun to come in, and problems such as crowding, deep bites and open bites can be detected.
Orthodontic evaluation at an early age provides one of two positive outcomes: For some, early identification of problems will lead to easier or shorter orthodontic treatment in the future. For others, a healthy prognosis will provide immediate peace of mind.

Early evaluation, of course, may signal a need for early treatment. For some children, early treatment can prevent physical and emotional trauma. Aside from spurring on years of harmful teasing, misaligned teeth are also prone to injury and are detrimental to good oral hygiene. So, if your child is nearing his or her seventh birthday, give us a call at 650-366-5758 to schedule an appointment that is free of charge.

Who Invented the Toothbrush?

    Who invented the toothbrush and when was it invented?    

  Various Peoples. 1938 (modern).

The toothbrush as we know it today was not invented until 1938. However, early forms of the toothbrush have been in existence since 3000 BC. Ancient civilizations used a "chew stick," which was a thin twig with a frayed end. These 'chew sticks' were rubbed against the teeth.
The bristle toothbrush, similar to the type used today, was not invented until 1498 in China. The bristles were actually the stiff, coarse hairs taken from the back of a hog's neck and attached to handles made of bone or bamboo.
Boar bristles were used until 1938, when nylon bristles were introduced by Dupont de Nemours. The first nylon toothbrush was called Doctor West's Miracle Toothbrush. Later, Americans were influenced by the disciplined hygiene habits of soldiers from World War II. They became increasingly concerned with the practice of good oral hygiene and quickly adopted the nylon toothbrush.
Some other interesting toothbrush facts:

• The first mass-produced toothbrush was made by William Addis of Clerkenwald, England, around 1780.
• The first American to patent a toothbrush was H. N. Wadsworth, (patent number 18,653,) on Nov. 7, 1857.
• Mass production of toothbrushes began in America around 1885.
• One of the first electric toothbrushes to hit the American market was in 1960. It was marketed by the Squibb company under the name Broxodent.

Invisalign Frequently Asked Questions

Invisalign Frequently Asked Questions

Invisalign can help you get the great smile you've always wanted because it's Invisible, so no one can tell you're straightening your teeth. So now you can smile more during treatment as well as after.

Q:	What is Invisalign?
A:	Invisalign is the invisible new way to straighten teeth without braces. Invisalign uses a series of clear, removable aligners to gradually straighten teeth, without metal or wires.
Q:	Does Invisalign really work?
A:	Yes. In both clinical research and in orthodontic and dental practices nationwide, Invisalign has been proven effective at straightening teeth.
Q:	How does Invisalign work?
A:	Invisalign uses 3-D computer imaging technology to depict the complete treatment plan from the initial position to the final desired position from which a series of custom-made Aligners are produced. Each Aligner moves teeth incrementally and is worn for about two weeks, then replaced by the next in the series until the final position is achieved.
Q:	What are the primary benefits of Invisalign?
A:	There are four primary benefits of Invisalign: Invisalign is nearly invisible - you can straighten your teeth without anyone knowing. Invisalign is removable - you can eat and drink what you want in treatment; you can also brush and floss normally to maintain good oral hygiene. Invisalign is comfortable - there are no metal brackets or wires to cause mouth irritation; no metal or wires also means you spend less time in the doctor's chair getting adjustments. Invisalign allows you to view your own virtual treatment plan before you start - so you can see how your straight teeth will look when your treatment is complete.
Q:	What are Aligners made of?
A:	Aligners are made of clear, strong medical grade plastic that is virtually invisible when worn.
Q:	What do Aligners look like?
A:	Aligners are nearly invisible and look similar to clear tooth-whitening trays, but are custom-made for a better fit to move teeth. Some orthodontists and dentists have referred to them as contact lenses for teeth.
Q:	Is this a new way to straighten teeth? How old is the company?
A:	For years, orthodontists and dentists have used removable appliances for limited treatment. Today, with the application of computer technology, Invisalign treats a broader range of cases with greater precision.
Q:	How old is the company?
A:	Align Technology, Inc., the company that manufactures Invisalign , was founded in 1997.
Q:	How old is this technology?
A:	In 1945 Dr. H.D. Kesling envisioned that one day, modern technology would enable the use of a series of tooth positioners to produce the kinds of movements required for comprehensive orthodontic treatment. Align has made this vision a reality. Using advanced computer technology, Align generates Invisalign, a series of customized appliances, called Aligners. Each Aligner is worn sequentially by the patient to produce extensive tooth movements in both upper and lower arches.
Q:	How many patients are being treated with Invisalign?
A:	Currently, doctors are treating more than 40,000 patients. The number grows daily.
Q:	Do doctors need special training in order to use Invisalign?
A:	While Invisalign can be used with virtually any treatment philosophy, specific training is needed. All orthodontists and dentists interested in treating patients with Invisalign must attend a workshop before cases will be accepted from their office.
Q:	How does Invisalign effectively move teeth?
A:	Like brackets and archwires, Invisalign Aligners move teeth through the appropriate placement of controlled force on the teeth. The principal difference is that Invisalign not only controls forces, but also controls the timing of the force application. At each stage, only certain teeth are allowed to move, and these movements are determined by the orthodontic treatment plan for that particular stage. This results in an efficient force delivery system.
Q:	Has the FDA cleared Invisalign?
A:	Yes, the FDA has reviewed our application and in August 1998 determined that Invisalign is exempt from 510(k) pre-market notification.

Can I Eat Candy With Braces?

Question: Can I Eat Candy With Braces?

You have braces and you want to sink your teeth into a gooey candy bar, but you wonder "Can I eat candy with braces?" If you've asked yourself this very question, the answer isn't too surprising.

Answer: There are many foods you can and can't eat with braces, but eating candy when you have braces is specifically not recommended for a number of reasons. Understanding why and how eating candy when you have braces will hurt your chances of having successful orthodontic treatment, thus affecting the health of your teeth and gums in the long run, will hopefully help diminish your cravings for sweet treats while you have braces; and hopefully beyond your orthodontic treatment as well.

It's All About the Sugar

For starters, let's take a look at the obvious. Candy is loaded with sugar, which is a carbohydrate. Carbohydrates are what fuel the bacteria on your teeth to produce acids that cause tooth decay to form. For a tooth without braces, candy is a large threat. Now add in the brackets and bands onto your teeth, which are a necessity during your orthodontic treatment, and your teeth most certainly will be facing a nightmare of tooth decay. When you incorporate additional sugar to your diet, along with the difficulty of reaching every surface of the tooth and around the bracket and band attachments with your toothbrush and floss, avoiding candy certainly outweighs giving into a tempting piece of candy.

Sticky, Hard, Gooey Gooey - It's All the Same

Candy can be found in a number of different forms, but it's really all the same when you consider eating candy with braces. From hard mint-type candies, to sticky toffee and gooey chocolate bars, candy does mass amounts of damage to your braces, regardless of what form it comes in.
When you bite into a hard or sticky piece of candy without braces, your tooth is stressed by the force it takes to break down and chew the piece of candy. With braces or your teeth, biting into a hard piece of candy will put additional force onto the bracket or band attachment, along with the tooth. More often than not, the bracket or band will succumb to the force it takes to eat the candy, and they will break or "pop" off. When a bracket or band becomes loose, your orthodontic treatment comes to a screeching halt until you are able to see your dentist or orthodontist to have he problem repaired. For most patients, a loose band or bracket will set their treatment back one to two months.
