Dental CrownsDo you have a broken, misshapen, or deeply discolored tooth? If you answered "yes," you may be interested in dental crowns! Crowns are caps, often made of porcelain, that dentists put on teeth in order to correct a number of dental issues as well as improve a smile's appearance. Dr. John Chu and Dr. Mary L. Lin in South Pasadena, CA, offer a full range of dental services, including crown placement. Read on to find out how dental crowns can help your smile!

1. Fix Dental Issues

Crowns are used to repair badly decayed, worn-down, broken, or damaged teeth. Crowns are also used to protect root-canal-treated teeth and as parts of a dental bridge. If you need crowns, see your dentist as soon as possible. Putting off treatment could jeopardize the health of your teeth and cause them to be damaged beyond repair. 

2. Beautify Your Smile

Dental crowns can also improve your smile by enhancing the appearance, alignment, shape, and color of your teeth. Crowns are made from several types of materials, including porcelain, ceramics, composite resin, or a combination of these materials, making them an attractive correction to any teeth that may be unsightly. 

3. The Luster of Real Teeth

Porcelain dental crowns can be matched to the color of your existing teeth. Your dentist can choose from many shades and give you a crown that is best matched to you. Nothing gives the same depth, translucency, and luster like porcelain dental crowns.

4. Durability & Strength

A dental crown acts as a strong covering for a tooth that has been damaged or weakened. Dental crowns can strengthen your damaged teeth and protect your weak teeth from fracturing. Crowns are known for their exceptional durability. Generally, crowns last between 10 and 15 years, and some crowns can even last a lifetime.

5. Improve Oral Function

If you have damaged teeth, you know they can keep you from enjoying the foods you love. It's difficult to eat and chew properly when you have fractured teeth, and dental crowns will give you the ability to chew all of your favorite foods again. They will restore the structure of your teeth so that you can eat in comfort and with confidence once again.

Damaged teeth are particularly fragile. If you don't take steps to protect them, they may eventually crack or fracture. South Pasadena, CA, dental crownsdentists Dr. John Chu and Dr. Mary Lin explain how you can avoid these consequences with dental crowns.

The problem

Damage to teeth doesn't have to be extensive or noticeable to put your teeth at risk. Even a small crack at the back of a tooth can increase the risk that it will break. Cracks weaken the structural integrity of your teeth. When you continue to use the tooth to bite and chew, the crack will grow. Eventually, a piece of your tooth will break off, or the tooth may even split in half. Whether your tooth is at risk of fracturing due to a crack or has already fractured or chipped, it's important to stabilize and restore it.

Crowns offer an excellent solution

Crowns not only improve the appearance of damaged teeth but also strengthen and support them. The tooth-shaped restorations are hollow inside and designed to slip over your damaged teeth. Before you can receive a crown, your tooth must be prepared to ensure that the crown can slide over it easily. Once your crown is cemented in place, it will protect your tooth by absorbing the strong forces you generate when you chew.

Porcelain, ceramic and porcelain-fused-to-metal crowns are very durable and tough enough to withstand years of wear and tear. In most cases, your new crown will last 10 years or longer before it must be replaced.

After your tooth has been prepared, we'll make an impression of your teeth in our South Pasadena office. The impression will be used to create a new crown that looks and feels perfectly natural. You'll probably leave the office with a temporary crown, then return in about two weeks to receive your permanent crown.

Crowns offer an excellent way to restore damaged teeth and improve their appearance. If you can benefit from a crown, call South Pasadena, CA, dentists Drs. John Chu and Mary Lin at (626) 799-0852 to schedule an appointment.

Are you wondering if you need a dental crown?

A dental crown is a prosthetic device used to cover a damaged or discolored tooth. Crowns are also placed over dental implants. There dental crownsare a number of reasons why you might need a dental crown, but it is a good idea to consult with a qualified dentist such as Dr. Chu  in South Pasadena, CA to see what is best for your situation.

A dental crown is a great option for protecting a tooth from further damage or decay. A tooth that has undergone a root canal, or a tooth that has a large cavity, compromised filling or even a chipped or cracked tooth can benefit from a dental crown.

In addition to the protection and preservation it provides for a tooth, a dental crown can also provide a natural looking cosmetic option for a damaged or discolored tooth. Because the crown is designed to your particular needs and specifications, your South Pasadena dentist Dr. Chu will be able to provide you a crown that closely mimics your natural tooth in shape, color, and function.

Crown procedures are usually done in two visits. During the first appointment, your South Pasadena dentist will examine your mouth, make an impression of the tooth, and prepare that tooth for the crown. That preparation usually involves some filing down or shaving and shaping of the tooth. He will then likely install a temporary crown until your permanent crown is ready. When your permanent crown is done – either in-house or at an outside specialty laboratory – your South Pasadena dentist will remove the temporary crown and replace it with the permanent crown.

Crowns last for a long time – five years or more – depending on the stresses you put on it. For example, if you grind or clench your teeth a lot, or practice poor dental hygiene, you might have failure issues sooner rather than later.

To keep your crown in optimum shape, practice good brushing and flossing habits, giving special attention where the crown meets your gum line. You should also avoid biting or chewing hard objects – ice cubes, popcorn kernels, for example.

Dental crowns provide stability and strength to your natural teeth.

Keeping your teeth healthy is the number one priority for Dr. John Chu and Dr. Mary Lin, your South Pasadena, California dentists. A dental crownlapse in regular dental checkups, poor eating habits or accidents can all affect the health of your teeth, leaving them vulnerable to further damage or total loss. However, dental crowns from your South Pasadena dentist can help restore the strength and function of your natural teeth. Here's how:

What are dental crowns?

Dental crowns have been a part of restorative dentistry since the late 1800s when they were referred to as "jackets." Both their names describe their basic function: to top off or cover a damaged natural tooth that cannot sustain any further dental work. They can be made from a variety of materials, including porcelain, ceramic or gold. Once they are designed and cemented into place over a tooth, they restore the aesthetic and practical properties of a tooth that were lost to trauma or decay. They can also be used as "abutments" for a bridge; the crowned teeth hold a false tooth, or pontic, in place where a tooth has been lost.

Why do I need a crown?

While you might easily adapt to losing one tooth, the loss will affect the rest of your oral health. Teeth need to be in a full set in order to function properly; otherwise, they tend to "drift" in an attempt to find a tooth with which to adjoin. Your jawbone needs the root system of each tooth to keep it stable. But with crowns from your South Pasadena dentist, even if the visible part of your tooth is damaged, the rest of your tooth is preserved. This translates into good long-term dental health.

If you think one or more of your teeth might benefit from crowns, don't delay in calling the dental offices of Dr. John Chu and Dr. Mary Lin in South Pasadena, California to schedule a consultation.

When a tooth is too weak to stand up to daily wear and tear on its own, a dental crown (a cap shaped like a tooth, varying in material) is used to protect it. From misshapen or yellowed teeth to decay, these crowns are needed in many dental situations, and are very common among children and adults alike.

There are many kinds of dental crowns, some with different purposes, prices and materials than others. They include, among others:

Porcelain-fused-to-metal:These crowns look more natural than metal, and the color can be matched to the existing teeth to lookDental Crowns more natural.
Stainless steel:These crowns are usually used as a temporary solution for protecting the tooth while a permanent crown is made. These are used primarily for children before their adult teeth come in. They protect the tooth until the "baby" tooth falls out to make room for the adult tooth. When the tooth falls out, the crown comes out with it, and a healthy tooth grows in its place.
All-resin:These crowns tend to wear down eventually, but are less expensive than other types. Many people get this type of crown with the intention of replacing it later.

The first step in preparing a tooth for a crown usually involves x-rays and a thorough examination of the tooth itself to check for large-scale decay, and to be sure the root of the tooth is healthy enough to support the crown. If the root is not acceptable, a root canal may be needed. Depending on the tooth, a temporary crown may be needed.

When the tooth is ready, it is first numbed, and then filed down to make room for the new crown. Impressions are taken of the tooth and surrounding areas and sent to a lab where the crown is manufactured. Once the dentist receives the crown back to their office, it will be cemented to the tooth permanently.

The tooth should be cleaned normally, and extra care should be taken when chewing foods or gum. Dental crowns can usually last anywhere from five to 15 years with proper dental hygiene and care. The cost of crowns varies depending on the type of crown used, but usually range from $600 to $1500.
