Can a kiss spread a cavity? The answer, according to dentist Dr. Vivian Menéndez, is yes… and no. The specialist in cosmetic and regenerative dentistry explains that, although cavities do not “stick” like a cold, the bacteria that cause them can be transmitted between people, especially through saliva.
“There are certain bacteria, specifically Streptococcus mutans, that are capable of destroying tooth enamel through the acids they produce,” explains Dr. Menéndez, founder of Art Dental Studio. “These acids are formed when food remains on the teeth, and bacteria take advantage of them to multiply.”
According to Menéndez, babies are born without bacteria in their mouths, so they usually acquire them from nearby adults, especially mothers, by sharing cutlery or kissing on the mouth. In this way, daily habits can facilitate the transmission of bacteria that eventually cause cavities.
“When we are adults, most of us already have Streptococcus mutans in our saliva, but for cavities to occur, dental plaque must also exist,” he clarifies. “That film of food debris that is not removed by brushing is the perfect environment for bacteria to act.”
The specialist highlights that cavities are a multifactorial infection, where hygiene, diet and care habits influence.
Kisses ruined by poor oral hygiene and poorly placed veneers have gone viral on social media. Among the most talked about confessions: bad breath, swollen gums and veneers that leave spaces where plaque and bacteria accumulate.
Dentists warn that these types of situations are not only uncomfortable, but also a reflection of serious oral health problems. Ill-fitting veneers can trap food debris and cause gingivitis, bad odor, or even cavities under the material.
The takeaway, according to experts: Before you get carried away with an Instagram-perfect smile, make sure your veneers are properly fitted, maintain a good brushing routine, and visit your dentist regularly. No one wants their kiss to go viral… for the wrong reasons.
Dr. Vivian Menéndez’s recommendations to prevent oral bacteria are simple but effective:
– Brush your teeth after each meal.
– Avoid sharing utensils or toothbrushes.
– Do not kiss babies or small children on the mouth.
– Visit the dentist regularly for cleanings and check-ups.
“Prevention begins at home,” concludes Menéndez. “Taking care of your oral hygiene not only protects your smile, but also that of the people you love most.”
