My husband is taking penicillan for tooth, can that cause me to get a yeast infection durning intercourse?

Pen and yeast inf.: The short answer is no. You can get a yeast infection if you take his penicillin. However, you can get a yeast infection just from having sex. The penicillin will have nothing to do with it unless you take the medication orally.

Never: You get yeast infections when you are contaminated by yeast, which is present in your stool & the environment. If people take a lot of abx, they can change the balance of good bacteria in their gut/body and allow yeast more room to grow. Your spouses penicillin has nothing to do with your risk of a yeast infection. Intercourse that may allow cross contamination with stool can increase risk of inf.
