ChangesinBoneStructurecanAffectDentureFit

It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.

Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.

Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.

There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.

A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.

EvenCelebritiesLikeJenniferLawrenceArentImmuneFromBadBreath

Exchanging passionate kisses with big-screen star Jennifer Lawrence might sound like a dream come true. But according to Liam Hemsworth, her Hunger Games co-star, it could also be a nightmare… because J.Law’s breath wasn’t always fresh. “Anytime I had to kiss Jennifer was pretty uncomfortable,” Hemsworth said on The Tonight Show.

Lawrence said the problem resulted from her inadvertently consuming tuna or garlic before the lip-locking scenes; fortunately, the two stars were able to share a laugh about it later. But for many people, bad breath is no joke. It can lead to embarrassment and social difficulties — and it occasionally signifies a more serious problem. So what causes bad breath, and what can you do about it?

In 9 out of 10 cases, bad breath originates in the mouth. (In rare situations, it results from a medical issue in another part of the body, such as liver disease or a lung infection.) The foul odors associated with bad breath can be temporarily masked with mouthwash or breath mints — but in order to really control it, we need to find out exactly what’s causing the problem, and address its source.

As Lawrence and Hemsworth found out, some foods and beverages can indeed cause a malodorous mouth. Onions, garlic, alcohol and coffee are deservedly blamed for this. Tobacco products are also big contributors to bad breath — which is one more reason to quit. But fasting isn’t the answer either: stop eating for long enough and another set of foul-smelling substances will be released. Your best bet is to stay well hydrated and snack on crisp, fresh foods like celery, apples or parsley.

And speaking of hydration (or the lack of it): Mouth dryness and reduced salivary flow during the nighttime hours is what causes “morning breath.” Certain health issues and some medications can also cause “dry mouth,” or xerostomia. Drinking plenty of water can encourage the production of healthy saliva — but if that’s not enough, tell us about it: We may recommend switching medications (if possible), chewing xylitol gum or using a saliva substitute.

Finally, maintaining excellent oral hygiene is a great way to avoid bad breath. The goal of oral hygiene is to control the harmful bacteria that live in your mouth. These microorganisms can cause gum disease, tooth decay, and bad breath — so keeping them in check is good for your overall oral health. Remember to brush twice and floss once daily, stay away from sugary foods and beverages, and visit the dental office regularly for checkups and professional cleanings.

So did J.Law apologize for the malodorous makeout session? Not exactly. “[For] Bradley Cooper, Christian Bale, yeah, I’ll brush my teeth,” she laughed.

Hemsworth jokingly agreed: “If I was kissing Christian Bale I probably would have brushed my teeth too. With you, it’s like, ‘Eh. Whatever.’”
