Hi Debcoco,
I work in a general practice and a periodontal practice (gum disease specialists). Most, if not all, OTC rinses are very ineffective. Listerine may have some germ killing properties, but they are very superficial and not very long lasting. It also contains quite a high percentage of alcohol which can increase a person's chances of oral cancer and is very drying to oral tissues.
The very best preventative of joint infections due to oral microbe invasion is very good home care of teeth and plaque control!! Concentrate your brushing efforts at the gum line (right where tooth and gum meet) this is where plaque forms. Good interdental (between the teeth) plaque control is important, too. Yes, (that four lettered word with five letters!) flossing. Tooth picks can be good for between teeth, too, but nothing can get under the gum like like floss. It is also important to have a professional cleaning of teeth at least twice a year (more often for gum disease patients) to get the tarter and plaque off that you cannot remove.
Plaque that is not removed sits on your tooth's gum line. Without you even know it (although sometimes there is visible bleeding) it causes microscopic gum bleeding (from the bateria's gum destroying waste products ) that allows the bacteria to enter the bloodstream. This is how it can (in theroy) get into vulnerable joints (ie- our implants). So even though mouthwashes can help by killing this bacteria, REMOVING it first, is our best protection!!
If you have serious dental concerns, (dexterity problems that prevent you from effectively removing plaque uncontrolled gum disease,etc.) then a mouthwash can help you. The standard one is by Rx only and is called Chlorhexidine gluconate (brand names:Peridex or Perioguard) You could ask your dentist if it would benefit you.
But... (Now I know I am going to get some gasps from this!!) the newest rage in US dentistry is a fabulously effective rinse that is safe (YES SAFE!!) to use for anybody (I have not heard of any contraindications, even pregnancy). All the practices I work in recommend it for all patients. It is inexpensive, easy to use, non-Rx, and we have seen amazing results ( less gum bleeding, less plaque, reduced gum disease, less cavities). It is a BLEACH and WATER mixture (look up Dr Slotts, who did all the research and developement).
ONLY NEED TO USE 2x A WEEK (ie- perhaps choose Sun and Weds) The germ killing effects are sustained for days after use!
Recipe: 1 teaspoon bleach (6%)
30 teaspoons water
3-4 teaspoons mint mouth wash (just so it tastes better)
( helpful hint- measure water and "mark the cup" then add mint and bleach)
After MIXING FRESH EVERY TIME YOU USE (mixing too early will make it lose it's effectiveness)
Take a mouthful (don't need to use entire mix) and swish for 30 seconds to 1 min
Then spit out
Again, it is safe, you only have to use 2x's a week, it is cheap, and no- it will not also whiten your teeth
We have had patients on it for about 2 years and have seen great results. Many report that it gets easier to use each time ( at first it tastes like "salty pool water")
Well, there it is. I would be happy to answer any more questions!

Be careful not to spit, drip on towels by sink or your clothing, as it may whiten/spot
