Frequently Asked Questions (FAQs)

How can we help you?

We want you to have all the information you need to make confident decisions about the direction of your dental treatment. Dr. Zadeh wants you to be informed and will always take time to explain what is happening with your oral health, why she recommends a particular treatment, and how it will benefit you. 

Patients like you come to us with many questions, and we have compiled some of the more frequently asked below. If you don't see yours here, we welcome you to contact our Tarzana dental office, and a member of our team will be happy to find the answer you need.


We are pleased to accept all PPO insurances at our Tarzana dental office. Maintaining healthy teeth and gums is crucial for overall health and wellness, and dental insurance often makes the difference between receiving and forgoing dental care.

At Dr. Zadeh’s office, we have dedicated staff who will review your coverage and ensure that you receive the maximum benefit. We are happy to provide pre-treatment estimates so you understand what your insurance covers and what it does not. We’ll also take care of filing your claim for you on your behalf and following up for payment if necessary.

Sometimes it’s helpful to have the option to extend your payments out over several months with financing. We are pleased to offer CareCredit, a third-party lender that offers options that allow you to receive dental care today and finance the balance. If you pay the balance within the agreed six-month period, CareCredit will not charge you any interest.

We would also be happy to explain our interest-free in-house payment plans offered on a case by case basis.

If you have insurance or financing questions, please call our Tarzana dental office at (818) 456-0039, and a knowledgeable member of our front office team will be happy to answer your questions.

Cosmetic Dentistry Tarzana, CA

Since everyone has a unique vision for their smile, a crucial part of treatment planning is listening carefully to your concerns. Some patients want a dramatic Hollywood-style makeover, while others prefer a few tweaks to bring out their smile’s natural beauty.

Whatever your goals are, Dr. Zadeh will create a treatment plan using one or more of the following services: 

  • Dental bonding
  • Tooth-colored fillings
  • All-porcelain dental crowns
  • Invisalign clear braces
  • Porcelain veneers
  • Teeth whitening

Cosmetic Dentistry in Tarzana, CA

Using cosmetic dentistry, we can alter and refine the shape, size, shade, and position of one or more teeth to create a more harmonious, symmetrical appearance. Tooth-colored fillings and dental crowns are often thought to be restorative, but they are so aesthetic that we often use them to repair broken, cracked, chipped, or gapped teeth. 

If you have mild to moderate tooth misalignment, we may be able to correct it with porcelain veneers or use Invisalign clear braces for more advanced treatment. For teeth that are stained, yellow, or discolored, we offer both in-office and take-home teeth whitening kits.

Dr. Zadeh and her dental team would love to meet with you to see how we can help you love your smile again. Please call to schedule an appointment for a cosmetic dentistry evaluation at our Tarzana dental office.

Crowns & Bridges Tarzana, CA

Our Tarzana dentist commonly recommends dental crowns to support, protect, and strengthen teeth that are broken, cracked, or have extensive decay. Sometimes referred to as “caps,” crowns are tooth-shaped shells of ceramic that cover and protect an entire tooth.

The general rule is that a dental crown is indicated if the damage affects more than 50 percent of the tooth structure. If you have a root canal on a tooth that absorbs a lot of chewing force, Dr. Zadeh would also recommend a crown to strengthen and protect it.

We also use crowns to support a dental bridge and to restore appearance and function to a dental implant.

The Process for Getting a Dental Crown

The process for getting a crown requires two appointments spaced about 2-3 weeks apart. During the first, Dr. Zadeh prepares the damaged tooth by altering its shape. Removing some tooth enamel allows for the bulk of the crown so that it sits flush against your gum line.

Next, we take impressions to create a mold of your teeth and choose the perfect shade of white to match your smile. We then send your case to a custom dental lab, where trained technicians meticulously fabricate your crown.

When your final crown comes back from the lab, we will ask you to return to our Tarzana dental office so Dr. Zadeh can adjust it for your dental bite, polish it, and cement it securely in place.

Do You Need a Dental Crown in Tarzana?

If you have a broken, cracked, or severely decayed tooth and think you need a dental crown, please call us to schedule an appointment with Dr. Zadeh.

Dental Implants Tarzana, CA

Nobody likes to think about tooth extraction, but sometimes it is the only option available to protect you and your long-term oral health. The good news is that we have more solutions than ever before to replace missing teeth and can customize one for your needs.

Replace Missing Teeth in Tarzana, CA

Because there’s often an emotional component to tooth extraction, we like to start talking about your replacement options before your procedure, if possible. Losing a tooth is a big deal but much easier to bear when you know that a solution is at hand.

  • Orthodontics to move teeth into the open space
  • Dental implants to permanently replace the missing tooth
  • A dental bridge that anchors to the two teeth adjacent to the missing tooth
  • Partial dentures - removable flipper, cast-metal partial, or clear bonded retainer

Of course, you always have the option of not replacing the tooth at all. While we don’t recommend this approach, we respect your right to make your own choices.

Schedule an Appointment to Learn More

Dr. Zadeh and her dental team understand that tooth loss can profoundly affect your comfort and quality of life. If you have already had a tooth extracted and want to discuss replacement options, please call our Tarzana dental office so we can help you.

General Dentistry Tarzana, CA

We commonly hear questions about dental x-rays from Tarzana patients who are concerned about the associated health risks. When you are Dr. Zadeh’s patient, we only take low-dose digital x-rays as part of your preventive dental care, to diagnose a new issue, or to monitor an ongoing condition.

The general recommendation for the frequency of bitewing x-rays is that every new patient has a full mouth series and that they are updated once a year. Since we create personalized treatment plans, however, you may require x-rays more or less frequently.

If you have a history of poor oral health, ongoing dental conditions, or active periodontal disease, Dr. Zadeh may recommend dental x-rays every 6-12 months. This ensures that our dentist has all the information she needs to provide the safest, most appropriate treatment.

For patients with excellent oral health and no signs of cavities and gum disease, we may only recommend new x-rays every two to three years.

Schedule Your Next Dental Exam

One of the benefits of an established dental home is having a dentist that understands you have unique needs and require personalized solutions. If it’s time for you to schedule your next checkup, please call our Tarzana dental office. If you need x-rays, rest assured that Dr. Zadeh will explain why she recommends them and what she hopes to learn.

Teeth Whitening Tarzana, CA

Our team will show you how to place the prescription-strength whitening gel in the trays and instruct you to wear them for about an hour a day. After two weeks of daily wear, you will be delighted to see a dramatically brighter smile and results that last.
