Saliva is a true workhorse among bodily fluids — it breaks down food for digestion, keeps harmful bacteria in check and neutralizes acid that is destructive to tooth surfaces. So when saliva flow is chronically diminished, it’s more serious than the uncomfortable feeling of “dry mouth” — it can have a detrimental effect on your overall health.
It’s normal to experience temporary mouth dryness: in the morning (because saliva flow slows during sleep), when we’re under stress, or after smoking or consuming certain foods and beverages like onions or coffee. But chronic dry mouth (“xerostomia”) is different — the mouth remains dry for extended periods, leading to problems like tooth decay caused by inadequate acid neutralization.
Medications are one of the most common causes for xerostomia. According to the Surgeon General, there are over 500 medications — both prescription and over-the-counter — that can cause it, including antihistamines, diuretics and antidepressants. Radiation or chemotherapy used for cancer treatment may also cause dry mouth, sometimes permanently. There are also systemic conditions that affect saliva flow like diabetes, Parkinson’s disease, cystic fibrosis, and many autoimmune diseases.
Treating chronic dry mouth will of course depend on the underlying cause. If drug-related the first approach should be to find a substitute medication that won’t as readily cause reduced saliva flow. If that’s not possible, then it’s helpful to drink more water when taking the medication (a few sips before and a full glass afterward). You can also cut back on caffeinated, acidic or sugary foods and drinks as well as alcohol, and refrain from tobacco use.
A saliva stimulant might also help. Besides prescription medication, there are other products like xylitol, a natural alcohol sugar found in chewing gum, toothpaste or rinses, that help increase saliva flow — and xylitol also inhibits the growth of decay-causing bacteria.
The most important thing for chronic dry mouth is maintaining consistent daily hygiene through brushing and flossing and regular dental cleanings and checkups. Helping to increase your saliva flow and making every effort to prevent dental disease will help keep this condition from harming your teeth and gums.

Periodontal (gum) disease is the most likely cause of a loose, permanent tooth. This progressive infection causes damage to the gums and bone tissues that hold teeth in place, leading to looseness and ultimately tooth loss.
Gum disease, however, isn’t the only cause: although not as common, excessive biting forces over time may also lead to loose teeth. The excessive force stretches the periodontal ligaments that hold teeth in place, causing the teeth to become loose.
This condition is called occlusal trauma. In its primary form, the patient habitually grinds or clenches their teeth, or bites or chews on hard objects like pencils or nails. Generating 20-30 times the normal biting force, these habits can cause considerable damage. It can also be a factor when gum disease is present — supporting bone becomes so weakened by the disease, even normal biting forces can cause mobility.
If you recognize the early signs of grinding or clenching, particularly jaw soreness in the morning (since many instances of teeth grinding occur while we sleep), it’s important to seek treatment before teeth become loose. The symptoms are usually treated directly with muscle relaxants, an occlusal guard worn to soften the force when teeth bite down, or stress management, a major trigger for teeth grinding. The sooner you address the habit, the more likely you’ll avoid its consequences.
If, however, you’re already noticing a loose tooth, treatment must then focus on preserving the tooth. Initially, the tooth may need to be splinted, physically joined to adjacent teeth to hold it in place while damaged tissues heal. In some cases, minute amounts of enamel may need to be removed from the tooth’s biting surfaces to help the tooth better absorb biting forces. Other treatments, including orthodontics and gum disease treatment, may also be included in your treatment plan.
If you notice a loose tooth, it’s critical you contact us as soon as possible for an evaluation — if you delay you increase the chances of eventually losing it. The earlier you address it, the better your chances of preserving your tooth.

Contrary to what you might think, a knocked out tooth doesn’t inevitably mean tooth loss. Time is of the essence — the shorter the interval between injury and replanting the tooth, the better the tooth’s long-term survival. The longer the interval, on the other hand, the less likely the tooth can survive beyond a few years. That phenomenon is due to the mouth’s natural mechanism for holding teeth in place.
The tooth root maintains its attachment with the jaw bone through an intermediary tissue known as the periodontal ligament. Tiny fibers from one side of the ligament securely attach to the tooth root, while similar fibers attach to the bone on the opposite side of the ligament. This maintains stability between the teeth and bone while still allowing incremental tooth movement in response to mouth changes like tooth wear.
While the ligament fibers will attempt to reattach to a replanted tooth’s root, the longer the tooth is out of the socket the less likely the fibers will fully reattach. An “ankylosis” may instead form, in which the root attaches directly to the jaw bone without the periodontal ligament. In this situation the body no longer “recognizes” the tooth and begins to treat it like a foreign substance. In all but the rarest cases, the tooth root will begin to resorb (dissolve); at some point (which varies from patient to patient) the attachment becomes too weak for the tooth to remain in place and is lost.
Ideally, a knocked out tooth should be replanted within 5 minutes of the injury (for step-by-step instructions, refer to The Field-Side Guide to Dental Injuries available on-line at www.deardoctor.com/dental-injuries). Even if you pass the 5-minute window, however, it’s still advisable to attempt replanting. With a subsequent root canal treatment (to remove dead tissue from the inner tooth pulp and seal it from infection), it’s possible the tooth can survive for at least a few years, plenty of time to plan for a dental implant or similar tooth replacement.
