Custom Fit Dentures
We offer our clients a full range of personalized professional denture services including:
Complete Dentures
Definition:
A denture is a removable replacement for missing teeth and surrounding tissues. Two types of dentures are available: complete and partial dentures. Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teeth remain.
Complete dentures improve the appearance of your smile, reduce wrinkles around your mouth, and are custom-made to your liking. Contact us today to discuss denture treatment options that are sure to make you smile.
Implants
Definition:
Denture implants are small titanium posts attached directly and permanently into the jaw which will act like roots for your denture. Your partial or complete denture is then snapped onto the implants providing more maximum stability and a secure fit.
Loose and sore dentures are difficult enough to contend with and losing your sense of taste because of them can also reduce your quality of life. Thankfully, there is a solution. Implant dentures provide the most chewing function possible because they support stabilized teeth and eliminate conventional denture challenges.
- Permanent teeth: A minimum of four implants would be placed in your upper or lower jaw, or both jaws. Your new teeth would then be secured to the implants. These teeth will not move or come out of your mouth. Think of it like having your natural teeth back! You even go back to brushing your teeth in your mouth again instead of in a cup by your bedside.
Your new teeth would take up considerably less room in your mouth in comparison to a conventional denture. This helps make them feel more comfortable and natural. Permanent teeth offer the ultimate in convenience, function and comfort.
- Removable dentures retained by implants: Implants would be placed in your upper or lower jaw, or both jaws. Your new dentures will “click” or “snap” onto the implants when you place them in your mouth; Think of it working like a button on a jacket.
You would need to place your fingers or thumbs underneath the dentures in order to pop or push them out of your mouth. Removable dentures on implants offer a drastic improvement in comfort and function in comparison to a denture without implants. Since you are still wearing a denture, however, you will still be able to experience all of the same issues that would typically be associated with dentures only these issues will happen much less. The dentures would still get loose, can get food underneath them and can still cause sore spots
Removable Partial Dentures
Definition:
A removable partial denture fills the gap between two healthy teeth and consists of replacement teeth attached to a gum-colored plastic base. Removable partial dentures are connected by a metal framework that helps keep them in place.
After losing one or more teeth, your remaining natural teeth can start moving into the adjacent empty space, which can cause bone loss around the root of existing teeth. Wearing a partial denture will fill gaps where a natural tooth might naturally move. Modern esthetic dentures provide you with dental solutions like invisible or clear clasps as well as dental implant dentures, so no one knows you’re wearing a denture.
If you have misshapen teeth, gaps between teeth, or teeth with deep discoloration, we can help with partial denture.
Immediate Dentures
Definition:
Immediate dentures are dentures that are made prior to someone having their teeth extracted.
We take impressions of your mouth while your natural teeth are still present. We then craft a denture in the likeness of your natural teeth and apply any necessary modifications to make that perfect smile! Immediate dentures are made in advance, so you can keep smiling the same day your teeth are extracted at the dentist office.

Denture Relines
SAME DAY
SERVICE

Same Day Denture Relining | Refitting
New dentures will typically fit your mouth very securely as it has been designed specifically for your gums. As time goes on, your gum tissues will change and the fit of the denture will become more loose and thus more prone to movement inside your mouth. Having your dentures professionally relined every 3 years, or when required, will keep the dentures secure and functional. We provide all our patients a complimentary cleaning and polishing of dentures if a relining is not required.
Denture Reline
All full dentures should have a hard reline done when the dentures become ill fitting. We would remove a layer of acrylic from the dentures interior surface,and then take a new impression of your mouth. The denture is then processed in our lab to the shape of your gum tissues. This results in maximum contact between the dentures and your gums!
The denture is then processed in our lab where it is adjusted to the new shape of your gum tissue. This results in maximum contact between the denture and your mouth.
Soft Reline
Some patients are unable to wear ordinary dentures because of tender gums or sore spots. We may recommend relining the denture with a material that stays pliable for several years before needing replacement. This material is much less likely to give the patient sore spots than the standard hard reline acrylic. Patients experiencing these problems may also consider a more permanent solution of implant retained dentures.
Temporary Relines
If dentures have not been serviced in quite some time, a patient’s gums may be red, swollen, or misshapen. This creates problems in taking impressions for a new hard or soft reline and may lead to a denture that would perpetuate the problem.
A temporary, or palliative (medicated) reline material may be recommended to allow the inflammation to subside. This reline makes the denture fit much more tightly and is usually soft and pliable. After a few weeks, the gums return to a more normal state. The patient is then ready for his new denture or hard reline.

Snoring
Comfortable and Effective Sleep Apnea and Snoring Therapy
If you suffer from snoring or Sleep Apnea, there are non-surgical, affordable and non-invasive treatment options available for you.
Permanent Oral Appliances are premium dental appliances developed specifically for the treatment of snoring and obstructive sleep apnea. These appliances resemble mouth guards and attach to both the upper and lower teeth with a mechanism that gently repositions the lower jaw forward to prevent the tongue and soft tissue of the throat from blocking the airway during sleep. They are an effective, comfortable and durable alternative to corrective surgery or CPAP (Continuous Positive Airway Pressure) therapy. They are inserted before going to sleep, then removed in the morning upon awakening.

Mouth Guards
THE RIGHT
PROTECTION

Mouth Guards
Protect Your Teeth!
How prevalent are sports-related dental injuries? In 2012, the National Youth Sports Safety Foundation (USA) forecast that more than 3 million teeth would be knocked out in youth sporting events that year! Among all the dental injuries we treat in children, it is estimated that over 25% are sports-related, and the majority of these involve the top front teeth.
Besides the immediate trauma, sports-related injuries can result in time lost from school and work, and substantial cost — up to $20,000 over a lifetime to treat a missing permanent tooth. Yet there’s a simple and relatively inexpensive way to reduce the chance of dental injury: A properly-fitted, comfortable mouth guard, worn whenever playing sports where the possibility of orofacial injury exists.
Use the Right Equipment
Athletic mouth guards.
What Type of Mouthguard Is Best?
The best mouth guard is one you or your child will actually wear, both at practice and on game day. There are several different types of mouth guards on the market, which generally fall into three categories:
- An “off-the-shelf” mouth guard. Available at many sporting goods stores, this type comes in a limited range of sizes, and varies widely in quality. The least expensive option, it offers a minimal level of protection that’s probably better than nothing. It generally must be clenched in the mouth, which can make wearing it uncomfortable and cause trouble breathing and speaking.
- The “boil and bite” mouth guard. These are designed to be immersed in hot water, and then formed in the mouth using finger, tongue and bite pressure. When they can be made to fit adequately, they generally offer better protection than the first type—but they may still be uncomfortable, and usually fail to offer full coverage of the teeth.
- A “custom-made” mouth guard. This is a piece of quality sports equipment that is custom fabricated for your mouth. How? Molds or impressions of your teeth will be made, and then tough, resilient, high-quality materials are perfectly fitted to that impression. This type of mouth guard offers you maximum protection and a superior level of comfort — and its cost is quite reasonable.
The Bottom Line – Protect Your Teeth!
When top-quality sports equipment can run in the hundreds of dollars, it makes more sense than ever to invest in the proven protection of a professionally made, custom-fitted mouth guard.
