Going to the dentist can be an intimidating experience. Our goal is that from the moment you enter our doors, you feel at ease and comfortable. Here, you’ll find answers to our most frequently asked dentistry questions. Whether you’re booking a new appointment or want to know about our dentistry services, we’re committed to helping you stay informed.

What is nitrous oxide (laughing gas)?

Nitrous Oxide, or commonly referred to as “laughing gas,” is safe and easy to administer. It is air (oxygen) mixed with medication usually carried through a mask that is inhaled through the nose. It has a sweet, faint smell that will take effect generally in about 5 minutes.

What is oral sedation?

Oral sedation is a pill taken that is safe and easy to administer. The medicine can be taken at home, in the office or both before a dental procedure. It also has a deeper level of sedation than nitrous oxide and can be combined with nitrous oxide for more effectiveness.

Who is a good candidate for light sedation?

Nitrous gas is safe for children and adults as an effective means to easing anxiety and creating a relaxed feeling while still being awake. Oral sedation is safe for adults who need a bit more sedation but not “asleep.”

How long does teeth whitening take?

On average, 6-8 weeks. But, everyone is different, depending on habits like drinking coffee and how often the gel is applied.

How long will veneers last?

High-quality, well-made porcelain veneers should last a number of years but everyone is different. It depends on your specific fracture risk as well as habits like biting into a hard candy or apple. Remember, dentistry doesn’t last forever and will need repairs throughout your lifetime.

How long does it take to get a new denture?

It depends on if you currently have a denture or if you are starting from scratch. It also depends on what type of denture you want. Implant-supported devices can take 3-6 months from implant placement while traditional dentures can take a month or more with multiple visits. We do not have same-day denture services.

Can I eat with Invisalign trays?

No. Patients must commit to wearing aligners 20-22 hours per day. That means you only have a few hours collectively each day to do all the eating and drinking (other than water).

How can I pay for my dental treatment?

You can make a payment via cash, check, a credit or debit card, or by utilizing one of our financing patterns, Care Credit and Alphaeon Credit.

How does your membership plan work?

Z Dentistry’s in-house membership plan provides a discount for patients without dental insurance. After joining, you will receive 15% off most services for up to 12 months. After your cleanings, you will also receive a free fluoride treatment. There are no maximums, deductibles, or claims. A discount is not applicable towards orthodontics, whitening, sedation, or snap on dentures.

Where are you located?

We are in Roanoke, TX directly off of 114 East near 35W. Our office is located in Chadwick Commons next door to BackPorch Drafthouse and PJ’s Coffee!

What are dental implants?

Dental implants are medical-grade, FDA-approved screws that integrate with the jawbone. Once the implant screw has settled in, a tooth can be fixed on top. And, unlike other solutions for missing teeth such as bridges or dentures, an implant won’t cause damage to the surrounding teeth.

You can replace a single tooth or use as little as four implants to replace all of your upper or lower teeth. Once the implants have settled in, you will be able to chew just as you did with your natural teeth.

How long does a dental implant procedure take?

While the initial surgical implant placement only takes an hour, the crown can’t be placed until 3-6 months later to allow for healing.

Am I a candidate for getting a dental implant?

If you are missing a tooth, have healthy gums, and adequate bone level, you are likely eligible. However, every person is different. After performing an exam, Dr. Smith can tell you.

How do crowns, bridges, and implants differ?

A crown is used over an existing tooth to improve or restore a tooth’s appearance and to prevent further decay or damage. A bridge fills in the empty space between natural teeth or implants that was left by a missing tooth.

Bridges are dependent on other teeth. Implants are independent of other teeth and are a permanent solution.

What is a root canal?

It’s a dental procedure where the inside of your tooth, the roots, are cleaned and disinfected where an infection is present. A covering will be placed over the access opening and, most of the time, a crown must also be placed over the tooth.

Do root canals hurt?
No — you will be completely numb before performing a root canal, which means you should not feel any pain. Sometimes, when a tooth has gone a very long time with an infection, there can be some pressure off and on but Dr. Smith will address your discomfort quickly.
What infection control procedures does Z Dentistry follow?
We follow all CDC guidelines for infection control. This includes but is not limited to:  Disinfecting all surfaces before and after every patient, sterilizing all instruments and using as many disposable products as possible, using proper hand hygiene and PPE guidelines. During COVID, we are also limiting patient interactions by spacing out appointments and not allowing visitors in the operatories (unless medically necessary). See our entire process here.
What is your cancellation policy?

In order to respect everyone’s time, we kindly request at least a 24 hour notice for all appointment cancellations and rescheduling. A fee may apply for appointments that are cancelled or rescheduled less than 24 hours prior to the scheduled appointment, no call no shows, and if you show up over 15 minutes late to your appointed time.


If I have a dental emergency, can I be seen right away?

Yes! We see patients on a same-day basis and walk-ins are welcome. We will see you as soon as there is availability, and we try our hardest to get you out of pain right away.
