Frequently Asked Questions (FAQs)

How can we help you?

Do you have questions about your dental health? We have answers!

We partner with our patients to help them achieve optimum oral health and we love to answer your questions about your smile. If you don't find the answer you need here, please feel free to contact Ava Chen, DDS today at (510) 886-3888 with your questions.


Dental x-rays are a vital part of your dental examination, and they offer valuable information for your dentist in Castro Valley to make an accurate diagnosis and treatment plan.

At Ava Chen, DDS, we have digital x-rays. This type of x-rays emits 75 percent less radiation compared to conventional x-rays. They are also safer for the environment since they don't require any chemicals for development.

Digital x-rays allow us to see things internally that can be missed with just the naked eye during an examination. X-rays allow us to detect concerns like tooth decay, cavities, and gum disease in their earliest stages, which then lets you treat these concerns with less invasive treatment procedures. 

Digital images are also readily available for viewing, so Dr. Chen can discuss any concerns with you immediately. This is very helpful in emergencies to determine the best course of action to restore your smile and dental health.

Dr. Chen recommends that standard bitewing x-rays be taken once a year because they provide a view of each tooth. Panoramic x-rays that provide a full image of your teeth, jawbone, and jaw joint are recommended every five years. Please contact our Castro Valley dental office if you have more questions about x-rays.

Your comfort is a top priority to Dr. Chen and her team. She is gentle and has over 20 years of experience in delivering pain-free dentistry to patients at our dental office in Castro Valley, CA.

If fear and anxiety are what keep you from visiting the dentist, Dr. Chen offers nitrous oxide to help you feel more relaxed. Delivered through an inhalation mask that is worn during your treatment, nitrous oxide helps "take the edge off" and is safe to use during most dental procedures for both adults and children. Better yet, nitrous doesn't interfere with your normal activities since it leaves your system quickly.

If you need more profound relaxation to help you complete your treatment, you can talk with Dr. Chen about using oral conscious sedation. We deliver this type of sedation with medication that is a pill you'll take an hour before your procedure. While you'll still be conscious and responsive, the drug induces deep relaxation to where you might even feel like you're sleeping. Most patients have little to no memory of their procedures when they use oral sedation.

At Ava Chen, DDS, we go above and beyond to ensure that you're comfortable in all aspects of your dental appointment. If you feel like you would benefit from using sedation dentistry during your appointments, please talk with Dr. Chen.

At Ava Chen, DDS, we never want finances to keep you from receiving the dental care you need, so we are happy to help our patients to budget their dental treatments. Your Castro Valley dentist does this by prioritizing dental procedures so you can do them in phases that you can fit easily into your budget and your schedule.  

We also work with CareCredit, which is a third-party financing company that allows you to pay for your treatment with affordable monthly payments over a period of time. CareCredit even has plans that are interest-free for qualifying patients. CareCredit is simple and quick to apply for either in our office or at home, and it is ideal for patients needing multiple procedures to restore their dental health, and our team is happy to help you apply for their service. 

You can also ask our treatment coordinator about pre-arranged installment payments. We are happy to work with our patients as much as we can to help them get the dental services they need. We also offer senior discounts.

Please contact Ava Chen, DDS today at (510) 886-3888 if you have questions or concerns about your treatment plan or would like assistance applying for CareCredit.

Children's Dentistry

At Ava Chen, DDS, we recommend early dental care, which keeps dentistry noninvasive and comfortable for our littlest patients. Dr. Chen likes to start seeing children at age 2 for an exam; we use a show and tell method that makes it a fun and exciting visit to the dentist. This means that we show your son or daughter exactly what we're doing and tell them what's happening before we get started. We never move forward with any type of procedure unless your child feels comfortable and ready for it.

We love supporting children through all stages of their dental development, and we offer additional services for children as they grow such as fluoride treatment and dental sealants. Our goal is to help your child build a healthy smile and protect their teeth. 

Your children's dentist in Castro Valley will also closely monitor your son or daughter's oral development to let you know if they might benefit from braces. She can also recommend a custom mouth guard for your child if they participate in sports.

We know it can be difficult for families to get the dental care they need in one place, and at Ava Chen, DDS, you'll find an environment where every member of the family can feel comfortable.

Dental Implants

Living with one or more missing teeth presents daily challenges that most of us take for granted. For example, chewing and eating food can be uncomfortable and even painful when you're missing a tooth. You may also feel embarrassed or self-conscious about the appearance of your smile.

There is also an impact on your dental health because neighboring teeth can begin to move and shift without a tooth replacement. Your jawbone will even begin to deteriorate without a tooth root to support.

Dental implants solve all of these problems by replacing both your tooth and your root with a replacement that looks, feels, and functions just like your natural tooth. This is one of the reasons why tooth implants are considered the gold standard in tooth replacement options.

If tooth implants are not a good solution, a dental bridge, partial, or denture may better fit your needs. Dr. Chen offers comprehensive implant dentistry at our Castro Valley dental office, and she can help you determine which tooth replacement option best suits your lifestyle, budget, and dental needs.

Contact Ava Chen, DDS today at (510) 886-3888 and schedule an evaluation with Dr. Chen to determine which tooth replacement solution is best for you.

Emergency Dentistry

Dental emergencies can be scary, inconvenient, and overwhelming! Castro Valley emergency dentist, Dr. Ava Chen, makes every effort to see you as soon as possible in the case of an emergency with convenient early morning and Saturday appointments. We also have instructions over the phone as to how you can contact us if your dental emergency occurs after hours.

Some of the dental emergencies in Castro Valley that we help with are:

  • Knocked-out teeth
  • Broken or chipped teeth
  • Cracked or broken dentures
  • Lost or broken dental crowns or fillings
  • Toothaches or tooth infections
  • Swelling or bleeding gums

We always encourage our patients to contact our dental office first in case of an emergency. Most hospital emergency rooms are not equipped to handle tooth emergencies, and typically, we can better provide you with the help and relief you need.

You can also avoid many dental emergency situations with consistent dental cleanings and checkups that allow Dr. Chen to detect many concerns earlier rather than later before they become a significant concern.

If you or a loved one is in pain or experiencing a dental emergency, contact our Castro Valley dental office right away at (510) 886-3888 for prompt emergency dental care.

Periodontal Treatment

Gum disease is essentially an infection of the gums and bone that support your teeth. It affects nearly half of American adults over the age of 35 in some form. In fact, gum disease is the number one cause of tooth loss in adults.

Just like a house, your gums and jawbone are the foundation that supports your teeth. When your support system becomes compromised, your teeth are at risk, and any restorative work you might need won't be very successful.

Gum disease occurs when bacteria enter in between your gums and teeth and cause an infection that gradually makes its way below the gum line and into your bone. This happens due to a poor diet and oral hygiene routine or habits like smoking or tobacco use.

If we detect in its early stages (gingivitis), gum disease can often be successfully managed with a thorough cleaning and an improved home care routine. In some cases, it can even be reversed.

If it advances to a later stage (periodontitis), it will require a more in-depth cleaning called scaling and root planing that removes plaque and tartar buildup underneath the gum line.

The good news is that Dr. Chen screens you for gum disease at every six-month checkup, so consistent preventive visits are your best defense against it. Contact our Castro Valley dental office today to learn more about gum disease.
