Tooth replacement options may include the following:
If missing teeth are leaving you feeling self-conscious or you wear dentures that are uncomfortable, dental implants can be a very effective solution.
Dental implants are designed to look perfectly natural alongside your other teeth. And they are a long lasting option for restoring your smile. The implant post is made up of titanium and other materials that are compatible with the human body. They are placed in the upper or lower jaw, where they function as a sturdy anchor for a replacement crown. Patients often rave about how their implants feel as secure, stable and natural as their original tooth. Dental implants can also be used in conjunction with dentures (implanted-supported dentures) providing a more stable fit that will give you confidence in your dentures.
Two types of dentures are available for the replacement of missing teeth. Full or complete dentures are used to replace full sets of teeth. When some natural teeth are still present partials can be used. Partials can be helpful to keep the remaining teeth from shifting.
Fixed bridges are a non-removable option to replace missing teeth. They are comprised of two crowns affixed to neighboring – or anchoring teeth. The artificial teeth then sit in between, replacing the missing teeth. They are strong and durable, but will need to be replaced after many years.

FAQs
What is myofunctional therapy and do I need it?
Myofunctional therapy is a series of exercises designed to improve the strength, coordination, and function of the tongue, lips, and facial muscles. It addresses issues like tongue thrust, mouth breathing, improper swallowing, or poor oral posture, which can contribute to dental problems, sleep apnea, or jaw pain.
You might need myofunctional therapy if you experience symptoms like chronic mouth breathing, speech difficulties, teeth grinding, or an open bite, or if your dentist identifies functional habits affecting your oral health. At Sandquist Dentistry in Las Vegas, Dr. Lee-Mirzayan, DDS, is certified in myofunctional therapy and, through consultation, will help you determine whether it’s right for you.
Does Sandquist Dentistry offer Invisalign?
Yes, we are a Gold Invisalign provider! Dr. Lee-Mirzayan straightens teeth and corrects mild to moderate bite issues with Invisalign custom-made clear aligners that gradually shift your teeth into place, like traditional braces but without metal wires or brackets. Request a free consultation with Sandquist Dentistry Las Vegas online.
Where do I go for emergency dental care?
At Sandquist Dentistry in Las Vegas, we do our best to accommodate dental emergencies. Start by calling our Las Vegas dentist office. When you call during office hours, we make every effort to see you, sometimes on the same day. If your dental emergency happens on the weekends or after office hours, don’t worry; just call the office and leave us a message. For true dental emergencies we have an emergency line that Dr. Sandquist monitors. He will return your call as soon as possible and see you at the earliest availability. For minor dental emergencies you can also request an appointment online. We do not see patients on weekends.
Do you pull teeth?
We do not pull teeth. During your consultation, if we see that you have teeth that need to be removed we will refer you to a trusted specialist and coordinate to ensure the restoration of your teeth.
What is full mouth rehabilitation?
Full-mouth rehabilitation is a comprehensive dental treatment plan that restores the function, aesthetics, and health of the entire mouth by addressing issues with teeth, gums, and bite alignment. It often involves a combination of procedures, such as crowns, veneers, implants, and periodontal treatments, tailored to the patient’s specific needs. Start by getting a consultation with a trustworthy dentist, like Dr. Sandquist. Though full mouth rehabilitation is not always necessary, digital imaging, X-rays, and a detailed assessment of your teeth, gums, jaw, and bite allow us to make a treatment plan. Restorative work (crowns, bridges, or implants), cosmetic improvements (veneers or teeth whitening), and functional corrections (orthodontics or TMJ therapy) are all part of your personalized treatment plan. At Sandquist Dentistry in Las Vegas, we are here to get your oral health, function, and appearance back to their best.
