No matter whether you are missing a single tooth or multiple teeth, you can rebuild your smile with dental implants! Read below to learn all Dental Implantabout the amazing benefits of this restoration method, and contact Dr. John Chu and Dr. Mary Lin in South Pasadena, CA, for personal treatment!


What are Dental Implants?

Dental implants are metal posts made from a hypoallergenic material, such as titanium. The posts are placed in the jawbone through a minor surgical procedure. There must be an adequate amount of bone to support the implant. Over time, the bone naturally begins fusing with the metal posts through a process known as osseointegration. This natural fusion process helps the dental implants remain securely in place, which is why they serve as such strong anchors for artificial teeth.

Once the bone and dental implants have completely fused together, the dental implants are ready to anchor artificial teeth in place. When just one tooth is being replaced with a single dental implant, that implant is capped with a dental crown. When multiple teeth are being replaced, bridgework or an implant-supported overdenture is placed over several dental implants.


Rebuilding Your Smile and More

The gaps in your smile that result when teeth are missing can lead to several different problems. One consequence of missing teeth is that speech can change. The teeth help control the placement of the tongue when speaking, so when there are gaps, the tongue can slip and distort the way a person sounds. Filling in the gaps with dental implants and artificial teeth can alleviate this problem.

Another problem that can occur when teeth are missing is that the shape of the face can change. Teeth provide support for the muscles in the face, so fewer teeth means less support. When there is less support, the cheeks can begin to droop and sag, causing a person to appear older. Filling in these gaps provides the much-needed facial support, and can thus restore the natural shape of the face.

Fixing these gaps also alleviates the strain on teeth that were compensating for the missing ones. Taking on the work of missing teeth can cause remaining teeth to become worn down more quickly. Luckily, dental implants help redistribute the work of biting and chewing across a full set of teeth, allowing for a long-lasting, healthy smile!

Very few people have a celebrity-like smile—normal wear and tear changes tooth shape and color over time and your genes also play a role in how your teeth line up and bite together. If you'd like your smile aesthetics to improve, the cosmetic dentistry services from Dr. John Chu and Dr. Mary Lin in South Pasadena could be for you! Their customized treatment plans make their patients smile!

What is cosmetic dentistry?

Cosmetic dentistry is a subspecialty of general dentistry. A cosmetic dentist's artistic services build on the foundation of a healthy smile and remake flaws such as surface pitting, odd shape and size, deep discoloration, cracks, gaps and more. Furthermore, cosmetic dentistry has gained tremendous popularity over the past three decades, which has lead to the treatments themselves becoming more and more predictable, realistic, and long-lasting.

When you see Dr. Chu or Dr. Lin, you'll discuss the simple or not so simple defects you'd like to makeover. Then, you'll agree on a plan which fits your goals. You can work through the entire plan all at once or spread out across multiple treatments over time as you wish.

Goals and treatments

If you wish to improve tooth color, Dr. Chu's Brite White in-office whitening treatments may be right for you. The one-hour service removes organic material embedded in tooth enamel. The proprietary whitening gel is activated by gas plasma light technology, and your teeth will become up to eight shades brighter.

If you wish to change tooth shape without a lot of fuss and muss, ask Dr. Chu or Dr. Lin about cosmetic contouring and composite resin bonding. The two services are often used together and are performed quickly right in the treatment room. Contouring uses small tools and fine grit sandpaper to smooth small surface and corner defects. Composite resin bonding, on the other hand, uses a tooth-colored putty to add proper shape and size to cracked or oddly shaped teeth or to fill in gaps. It's hardened with a special blue light and is the same material used in tooth-colored fillings.

Finally, porcelain veneers are thin, translucent shells of premium ceramic. Customized to cover the front of teeth that are marred by a wide range of flaws, veneers permanently improve the shape, color, and size of healthy teeth. Veneers do require enamel resurfacing but far less than porcelain crowns do.

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.

Dental Implants to Replace Missing TeethSmile gaps look unattractive, and they compromise remaining teeth and how you chew and speak. If you are missing one, two, or even more teeth or think extractions are in your future, consider dental implants from Dr. John Chu and Dr. Mary Lin, your South Pasadena, CA, dentists. Truly, these modern tooth replacements are amazingly close to real teeth.

What are dental implants?

They are artificial teeth having three components: a root (the titanium implant device itself), an extension post and a custom-fabricated porcelain crown. Your South Pasadena dentist inserts the dental implant screw into the jaw bone, anchoring it permanently in place.

Because titanium and human bone are highly compatible, they bond together through something called osseointegration. While osseointegration takes time, it practically guarantees the implant's success and longevity.

The Institute for Dental Implant Awareness states that 95 to 98 percent of single-tooth implants will last 40 to 50 years. Conventional tooth replacements, such as bridges and partial dentures, typically fail within 15 years because they lack adequate support. Dr. Chu and Dr. Lin place single-tooth implants and multi-tooth bridges and dentures supported by implants.

Placing a dental implant

Take, for instance, the single implant procedure. It's done in its entirety at our dentists' office following a complete oral examination and X-rays to determine if the jaw is sufficiently dense to support the implant.

An access hole in the jaw allows for implant placement and after healing, bonding of the extension post and crown. Healing and osseointegration takes many weeks, and some patients wear provisional crowns in the meantime to complete their smiles.

On the return visit, our dentists check for proper osseointegration. If all is well, they bond the permanent crown onto the metal alloy extension post.

Caring for an implant or implant-supported denture

Daily oral hygiene is critical to implant success. Just as with your natural teeth, good brushing and flossing habits decrease plaque and tartar accumulation and avoid gum and bone infections (implants do not get cavities). You should see your dentist twice a year as usual for examinations and professional cleanings, and if you grind your teeth, ask Dr. Chu or Dr. Lin about a bite guard. A bite guard reduces the stresses on your implant and the rest of your smile, too.

Don't delay

Dental implants from Dr. Chu or Dr. Lin and their caring team really do fill gaps, beautifying your smile and avoiding the bone and gum deterioration which happens after tooth loss. To find out more, please call their South Pasadena, CA, office to arrange your consultation. Phone (626) 799-0852.

Dental VisitsMany people find it difficult to pencil their dentist into their busy schedule. However, visiting the dentist for regular examinations and cleanings is crucial to your oral health and help you keep teeth decay and gum disease at bay. Do you visit your dentist enough? Is your oral care routine enough to keep your teeth healthy? Find out the answers to these questions and more with Dr. John Chu and Dr. Mary Lin in South Pasadena, CA.

How often should I see my dentist? 
According to the American Dental Association’s recommendation, you should have a dental examination and cleaning every six months. This is a blanket recommendation, meant for every dental patient regardless of their dental needs or history. Some patients, such as those who are more susceptible to gum disease or teeth decay or have a history of severe dental problems, may need to see their dentist even more frequently. Some people, who have a very strong at-home oral care routine and history of good dental health may be able to get away with only one visit a year. Work with your dentist to determine the best examination schedule for your particular needs.

How should I care for my teeth? 
Caring for your teeth is a daily two-step process. Brush your teeth at least twice a day using a soft toothbrush and ensuring that each brushing session lasts at least two minutes. Use good technique, including brushing the fronts and backs of every tooth, including the backside of the back molars, and using short, back-and-forth motions to clean each tooth. Floss between each tooth at least once a day. Use a long strand of floss wrapped tautly around your two forefingers to floss between each tooth and extend the floss all the way up and under the gums to help remove bacteria build up in those areas. If you have special circumstances like very crowded or overlapping teeth or a dental restoration like a bridge, you may need to use specialized tools like threading floss or a water pick to ensure your teeth are thoroughly clean.

Preventative Dental Care in South Pasadena, CA
Preventing teeth decay and gum disease is an ongoing fight which requires daily attention. Your dentist simply picks up your slack and ensures you have a clean slate to work with between visits. Work together with your dentist to ensure that you have the best oral care routine and dental examination schedule for you and your smile.
