The short answer is: oral hygiene significantly impacts the kissing experience, while the straightness or cosmetic appearance of teeth plays a less crucial role.
The Importance of Oral Hygiene
As noted in various sources, kissing involves the exchange of saliva, and poor oral hygiene can lead to the transmission of bacteria causing gum disease and cavities. This is a crucial factor to consider. Bad breath is another significant deterrent, frequently mentioned across several discussions and articles (Baremarriage.com, Reddit). Therefore, brushing your teeth before kissing is essential for a pleasant and hygienic experience.
The Role of Tooth Straightness and Appearance
While some sources express concerns about hitting teeth during a kiss (Quora, TikTok), this is more of a matter of technique and adjustment than an inherent problem. The impact of crooked teeth on kissing is subjective (Prince.org). Ultimately, confidence and connection are far more important than perfectly straight teeth. One Quora user notes that a kiss is an expression of affection regardless of oral hygiene (Quora).
In Summary
The overall enjoyment of a kiss is far more influenced by oral hygiene and mutual affection than the cosmetic appearance of teeth. While colliding teeth can be a minor inconvenience, easily overcome with practice, consistently bad breath and potential transmission of bacteria significantly impact the kissing experience.
