Losing a tooth can be a traumatizing situation, not only because of the pain or discomfort but because of the gap it leaves behind. dental implants\However, you can fill in your gaps and get your smile back with dental implants. Find out more about dental implants with Dr. John Chu and Dr. Mary Lin in South Pasadena, CA.

Do I need dental implants? 
Do you have a gap in your smile? Are you missing more than one tooth? Are you missing all of your teeth? If you answered yes to any of these questions, you might benefit from dental implants. Implants can replace a single tooth using one implant, several teeth in a row using a dental bridge with an implant on either side or even an entire arch of teeth using an implant-supported denture.

Are dental implants right for me? 
Since dental implants require a surgical procedure, you should be in good health and able to undergo the procedure and healing process without complications. Missing teeth cause bone atrophy. Implants require a good bone volume since the implant requires a sturdy foundation in which to sit. A good candidate for implants should have an adequate amount of bone left below their missing tooth. If there is not enough bone remaining, your dentist may suggest a bone graft procedure to rebuild the area of the implant. In this case, you will have a separate procedure for the bone graft prior to the implant’s procedure.

Dental Implants in South Pasadena, CA
Dental implants are a permanent and effective tooth replacement solution which, with the proper care, will last a lifetime. However, a strong at-home dental care routine including brushing twice daily and flossing at least once and regular dental examinations and cleanings are crucial in keeping the implants healthy. Don’t let a lost tooth haunt your smile. For more information on dental implants, please contact Dr. Chu and Dr. Lin in South Pasadena, CA.

Find out why you might need root canal therapy.Root Canal


Has one of our South Pasadena, CA, dentists Dr. John Chu or Dr. Mary Lin just told you that you need root canal treatment? If so, you may be scratching your head wondering what happened. Root canal treatment is actually a very common endodontic procedure, with around 15 million people undergoing this treatment each year. Find out why root canals are performed and why they might be necessary for the health of your teeth.

What is the purpose of a root canal?

The goal of this endodontic procedure is to treat problems that are occurring within the tooth. Below the hard enamel layers of a tooth lies a structure that is known as the dental pulp. The pulp is a tissue that contains the nerves of the tooth. While the pulp is important for the tooth while it is developing, once the tooth has fully matured, the root canal is no longer necessary for the tooth to survive.

Why do I need root canal therapy?

There are many situations in which the dental pulp can become inflamed or infected including decay, injury, an infection or a crack/chip in the tooth. If the problem is left untreated, not only will you most likely notice severe dental pain but also an abscess may form (a pus-filled growth) around the infected tooth. To prevent the tooth from needing to be extracted in the near future, our South Pasadena, CA, general dentist will recommend root canal treatment.

What are the steps involved in this endodontic procedure?

We will first need to run X-rays to determine whether the pulp is infected/inflamed. If this is the case, we will numb the tooth using a local anesthesia. This will ensure that you don’t feel any discomfort during your procedure.

Once the treatment area is completely numb, we will make a hole in the crown of the tooth so that we can enter the inside of the tooth. Once inside the tooth, we will remove the pulp and disinfect the tooth and root canals. Once the tooth has been cleaned out, we will fill the root canals with a special material to make sure that another infection doesn’t occur.

Once the tooth has been filled the last step will be to make a dental crown for the tooth and to cement the crown over the tooth to restore it.

Are you noticing a toothache that just won’t go away? If so, this could be a warning sign. Any changes to your oral health should be assessed by our South Pasadena, CA, general dentists right away. Call our office today.

Why let your smile be anything less than perfect when there’s cosmetic dentistry?cosmetic dentistry

Most people end up just putting up with cosmetic imperfections in their smile because they don’t really know what their options are to change it. Our South Pasadena, CA, cosmetic dentists, Dr. John Chu and Dr. Mary Lin, are here to explain the different options that are out there so you know what we can do to help your smile.

Dental Stains

No one wants a yellow smile and yet it happens over time. Maybe you just can’t tear yourself away from that coffee or you quit smoking but are still faced with nasty discolorations. Don’t worry; our South Pasadena dentist has you covered.

If you have external stains (yellow or brown stains), this can easily be treated with professional teeth whitening. Choose from our in-office whitening system if you want significant whitening results quickly, or opt for our at-home whitening system if you prefer to do it from the comfort of your own home.

Tooth Loss

Nothing is more embarrassing than having gaps in your smile where your teeth used to be. If this has happened to you, it’s important to know that you have options. If you are willing to wait a few months to get a tooth replacement, then choose dental implants, which is the closest thing you can get to real teeth. They offer an amazing array of benefits including preserving jawbone health and preventing changes to your facial structure.

Of course, dental bridges and even dentures can be ideal options for patients who may not be ideal candidates for implants. These restorations have stood the test of time and continue to be a popular way to replace one or more missing permanent teeth.

Misshapen or Uneven Teeth

From cracks and chips to gaps in your smile, there are many imperfections that can befall you at any point in time. Luckily, dental veneers can be bonded to the front of your teeth to cover gaps, discolorations, malformed teeth, minor overlapping or crooked teeth, as well as cracks, chips and fractures. These porcelain shells are made to look just like the surface of your teeth and are custom-made to cover over each front area of an individual tooth.

Do any of the cosmetic services above sound like exactly what you’ve been looking for? We thought so! If you are interested in what we can offer you then call our South Pasadena, CA, cosmetic dental office today and book an appointment with us.

Isn't it about time you treated yourself to the smile you've always wanted? If you don't like the way your smile looks, you'll want to veneersconsider porcelain veneers. South Pasadena, CA, dentists, Dr. John Chu and Dr. Mary Lin, explain how veneers can enhance your smile.

A simple way to change your smile

Slipcovers are the ideal solution if your couch is stained or torn. After you carefully arrange the new cover, no one will ever know what problems lurk underneath. Porcelain veneers are just as effective at hiding the little flaws that affect tooth enamel. Because they're no thicker than a fingernail, veneers are very light and comfortable. Custom-made veneers are attached to the fronts of teeth with dental cement and easily conceal many dental imperfections.

No more gaps

No matter how small they are, gaps between your teeth can make you feel a little self-conscious. After your new veneers are applied at our South Pasadena office, you'll soon forget you even had any spaces in your smile.

An easy way to brighten dull teeth

Do you sipping on coffee throughout the day? The dark pigments in certain beverages, such as coffee, tea, wine and cola, can stain teeth. Teeth whitening treatments offer one way to lighten your smile, but whitening results only last a few years. Porcelain veneers provide a long-lasting, stain-resistant alternative to teeth whitening. A single veneer can also be used to improve the appearance of one tooth that has darkened due to taking tetracycline or as a result of dental procedure.

Damage disappears

Wear and tear on your teeth can cause cracks and chips. Your new veneers will transform your smile by concealing minor damage that can mar your smile.

Veneers lengthen teeth

A discrepancy in the length of your teeth can have a big impact on your smile. Often the problems occur if you grind your teeth at night. Grinding wears down tooth enamel, shortening teeth. In addition to lengthening your teeth with veneers, you'll also want to wear a nightguard while you sleep to prevent further enamel erosion or a cracked veneer.

Upgrade your smile with porcelain veneers. Find out if this cosmetic dentistry option will solve your dental problem by calling South Pasadena, CA, dentists, Dr. Chu and Dr. Lin, at (626) 799-0852 to schedule an appointment.

According to the American Dental Association (ADA), more people are keeping more of their natural teeth longer than at any point since the 1970s, but gum disease-related tooth loss still affects millions of adults every year. Data collected by the Centers for Disease Control and Prevention (CDC) found that as many as half of American adults are suffering from some form of gum disease, ranging from mild gingivitis to full-blown periodontitis, the leading cause of tooth loss in adults over the age of 35. Adults over the age of 65 may be at higher risk, but younger people are not immune. Dr. John Chu and Dr. Mary Lin, dentists in South Pasadena, CA, offer several tooth replacement and dental restoration options like dentures and dental implants.

Restore Your Smile and Oral Health with Dentures in South Pasadena, CA

Whether tooth loss happens as a result of gum disease, severe tooth decay, or an injury, there is no "one size fits all" when it comes to dental restorations. There are several types of dentures that allow a dentist to design the perfect model for each patient's unique dental needs and lifestyle. For some, dentures may conjure an image of an older person missing all of their natural teeth, but in reality, there are options for every degree of tooth loss, which can happen at any age.

Dr. Chu and Dr. Lin offer three main types of dentures:

  • Full (complete) dentures
  • Partial removable dentures
  • Implant-supported overdentures

Immediate dentures are a temporary pair that can be custom fit for immediate use until the permanent set is ready.
