In brief: No.

Dental caries is the result of bacteria settling onto teeth and metabolizing the foods you eat.
The end product of that metabolism is acid that then demineralizes your tooth structure. Some bacteria makes more acid than others. But the kind of bacteria you have is determined when you're a child. Exposure to someone else's bacteria won't change the bacteria that lives in your mouth.

In brief: Yes it is possible

Despite what has been stated, it has been shown by many scientific studies that the bacteria that cause dental decay are transmissible at any age to any one.
That is a fact. The reality is as to whether you will develop caries in your mouth. It depends on your oral saliva, ph, proteins, etc. If your system can't handle the stress, decay will occur. Always try to maintain good oral hygiene habits!

In brief: No

Cavities are not transmitted by kissing.
But the bacteria that caused the cavities in one person can be transmitted. If you don't follow good dental hygiene (proper brushing & flossing), you are at risk for dental caries - but that is regardless of whether you kissed the person with cavities or not.
