All taste buds on the tongue can detect all five basic tastes: sweet, sour, salty, bitter, and umami.
Therefore, it's not possible to say how many taste buds specifically detect sweetness.
However, we can tell you that:
* There are roughly 10,000 taste buds on the average human tongue.
* These taste buds are distributed across the tongue, soft palate, and even the back of the throat.
It's important to remember that taste is a complex sense, and many factors influence how we perceive flavors, including smell, texture, and temperature.
