When a device meant to make your life easier doesn't function properly, it can be extremely frustrating. This is sometimes the case for people who wear lower dentures, which loosen over time. These removable replacement teeth can become less reliable and more uncomfortable. Why does this happen?
The answer is bone loss. When a tooth is lost, the bone surrounding it deteriorates and this will change the shape of the jawbone in your mouth. You may find that a lower denture that once had a snug fit on your lower jaw is now sliding around. This happens more often on the bottom because your muscular tongue pushes against the denture. Also, a top denture has more surface area due to an artificial palate to help create suction to the roof of the mouth and keep it in place.
Dental implants, which permanently replace the roots of teeth, do not loosen and they also prevent bone loss. But replacing a whole set of bottom teeth with dental implants and crowns is expensive. What to do?
There's a relatively new solution that combines the security of implants with the affordability of a removable denture. It's called an overdenture, and it may be something you want to consider. An overdenture is a lot like the removable lower denture you already have, only it fits over two implants strategically placed in your lower jaw. While the lower denture is still removable, its stability is greatly improved.
Studies have shown that people with two-implant overdentures have a higher quality of life, and receive better nutrition, than those wearing conventional dentures. It's not hard to figure out why: A more stable denture makes it easier to eat healthy foods such as vegetables — or, really, any foods — and prevents embarrassing slippage of false teeth.

Ensuring that your children have good oral health is (or should be) the goal of every parent or caregiver. But how confident are you about this topic? The following true/false quiz will help you evaluate your expertise while learning more about keeping your child's teeth healthy.
- All children older than 6 months should receive a fluoride supplement every day.
- Parents should start cleaning their child's teeth as soon as the first tooth appears.
- Parents should start brushing their child's teeth with toothpaste that contains fluoride at age 3.
- Children younger than 6 years should use enough toothpaste with fluoride to cover the toothbrush.
- Parents should brush their child's teeth twice a day until the child can handle the toothbrush alone.
- Young children should always use fluoride mouthrinses after brushing.
- False. Check with your child's physician or dentist about your children's specific fluoride needs. If your drinking water does not have enough fluoride to help prevent cavities, parents of a child older than 6 months should discuss the need for a fluoride supplement with a physician or our office.
- True. Start cleaning as soon as the first tooth appears by wiping the tooth every day with a clean, damp cloth. Once more teeth erupt, switch to a small, soft-bristled toothbrush.
- False. Parents should start using toothpaste with fluoride to brush their childrenÃ¢Â€Â™s teeth at age 2. Only use toothpaste with fluoride earlier than age 2 if the child's doctor or our office recommends it.
- False. Young children should use only a pea-sized amount of fluoride toothpaste. Fluoride is important for fighting cavities, but if children younger than 6 years swallow too much fluoride, their permanent teeth may develop white spots. Using no more than a pea-sized amount of toothpaste with fluoride can help prevent this from happening.
- True. Because children usually do not have the skill to brush their teeth well until around age 4 or 5, parents should brush their young children's teeth thoroughly twice a day. You should continue doing this until the child can demonstrate a proper brushing technique.
- False. Fluoride mouthrinses have a higher concentration of fluoride than toothpaste containing fluoride. Children younger than 6 years of age should not use fluoride mouthrinses unless your child's doctor or our office recommends it. Young children tend to swallow rather than spit it out, and swallowing too much fluoride before age 6 may cause the permanent teeth to have white spots.

If you are insecure about your misaligned crooked teeth, then you may be a perfect candidate for clear orthodontic aligners. This system is an alternative to traditional braces that uses a sequence of individual, clear, removable “trays” that fit over your teeth to gradually straighten them. Each tray is completely clear and covers all the teeth thus making it virtually invisible. Each tray is designed to slightly move the teeth until the teeth are in proper alignment. Typically, each tray must be worn for 20 hours a day for 2 weeks before progressing to the next tray in the sequence with each tray moving you closer towards your goal — perfectly aligned teeth.
However, clear orthodontic aligners are not for everyone. If you are interested and wonder if they can benefit you, contact us so that we can schedule an appointment for a thorough evaluation to assess your specific situation. Below, we have briefly outlined some situations when they will and will not work.
Clear orthodontic aligners work if...
- You have mild to moderate crowding or spacing issues between teeth
- Back teeth fit together properly
They may not be the right choice if...
- You have moderate to severe crowding or spacing issues between teeth
- When your bite does not align properly (for example, if you have a large over-, under-, or cross-bite)
- When your teeth are “rotated” way out of position; such misaligned teeth will require special or complex techniques to rotate them back into position, or to pull them down into place or to fill the space left after pulling a tooth to resolve excessive crowding of teeth

We tend to think of aspirin as a harmless medication. It is dispensed over the counter and is the most widely used OTC medication in the U.S. We take it without thinking we may be exposing ourselves to risks. But in certain situations aspirin can cause dangerous side effects.
What is aspirin, and how does it work?
The chemical name for aspirin is acetylsalicylic acid. It is used to reduce mild pain, inflammation and fever. When you take an aspirin, it blocks the formation of prostaglandins, substances your body creates that are associated with inflammation. Prostaglandins cause inflamed tissues to become red and swollen, but they also serve protective purposes, such as forming a barrier that protects the stomach from the acid it produces to digest your food. That's why long-term aspirin use can sometimes cause stomach bleeding and ulceration or other health problems.
Why do cardiac patients take aspirin?
Another effect of aspirin is to prevent blood platelets from clumping together. Blood platelets are structures in the blood, smaller than white or red blood cells, that aid clotting by sticking together at the site of an injury. This effect of aspirin can cause prolonged bleeding, but it may be beneficial to people who have cardiovascular (from cardio, meaning heart; and vascular, meaning vessel) disease with narrowed blood vessels.
Aspirin can keep blood flowing in the obstructed vessels and thus prevent heart attacks and strokes; but it can also increase the risk for strokes that are caused by bleeding in the brain. Most physicians attempt to lower such risks by asking their patients to keep their daily aspirin consumption to a low dose 81 mg “baby” aspirin.
How does aspirin affect your teeth and gums?
Be sure to let your medical and dental professionals know you are taking aspirin, and how much you take. Also tell us about other OTC medications you take, including herbal medications and supplements, because they may interact with aspirin to cause side effects.
If you have been told to take aspirin because of a cardiac condition or procedure, be sure to follow your recommended treatment. Do not suddenly discontinue aspirin therapy; doing so can increase your risk for heart attack and stroke. Ask us if you should stop taking aspirin before a major dental or oral surgery, but do not stop taking it on your own. We will consult with your physician about your medical condition and let you know our recommendation. In most cases you can continue your aspirin therapy without causing excessive bleeding during the dental procedure.
