This is a story that is about romance as much as it is about friendship. We have classic setup of 3 best friends with different personalities, and their respective pairing. The couples are
1) The typical 傻白甜 (silly, innocent, sweet) librarian Zeng Li paired with the straight laced and serious dentist Ai Jing Chu
2) Boyish Dr. Wu Ying with a 6 years younger university student Liu Yu Cheng
3) Influencer, sexy Ma Yi Yi on an off-on relationship / chemistry with entrepreneur playboy Deng Hao Ran

The story explores 3 different types of relationship pairing dynamics, as well as the friendship that the characters build and share with each other. There isn't anything novel about the plot or script - in fact, the classic meet-cute between Zeng Li and Ai Jing Chu is like your everyday rom-com scene. Nothing you have not watched before if you are a veteran in the rom-com genre.

What makes this series a slight cut above the other rom-com I watch is the friendship that 3 ladies share, as well as the exploration of 3 types of different pairings in 1 story. The acting of the leads are good too, considering the cast veer on the younger side.

Although, if I am allowed to nitpick one thing, it would be the title of this series. This series is original adaptation from a novel named "A Speck Amid the Dust of the World". I don't know what makes the production team decide on the name Sweet Teeth for the drama adaptation of it. Primarily because to me, the teeth and main lead's occupation as Dentist were only plot devices for Zeng Li and Ai Jing Chu to meet and get to know each other. As the story progresses, I barely even remember Zeng Li was forced to get braces or that Ai Jing Chu is a dentist.

The real message that I feel this story wants to portray is - in this vast world, my life becomes meaningful after I met you. And they (cast and production team) did well.
