Actually your best bet believe it or not is to remove the yeast infection from your entire system, using a natural oral treatment to balance the yeast in your entire system.
Yeast infections aren't that easy to permanently get rid of. Many products can temporarily relieve the symptoms, but a long term treatment approach will be your best bet to completely eliminate it. Otherwise the chances of the yeast infection reoccuring are pretty high.
One of the more popular and effective homeopathic solutions is yeastrol. It's very effective at treating vaginal, penile and oral yeast infections.
What you can also do to speed your recovery is to change you diet in a way that will starve the yeast organisms (Candida).
Things that you should remove from your diet are all sodas, sugars, fruit, fermented foods, foods containing white flour, alcohol (especially beer), antacids and any product that has yeast or mold.
Things to add to your diet are live yogurt cultures (or take Acidophilus), plenty of water, fresh vegetables, lots of protein rich foods, whey protein, raw garlic, nuts, seeds, oils, millet, rice and oat brans
Another thing to keep in mind is that both you and your partner should consider the diet change/yeastrol treatment as you can be passing the infection back and forth between you.
Hope this helps and best of luck! :)
