It's best to give priority to liquid food about two days after wearing a tongue nail, because I'm not used to having a nail on my tongue, my tongue will swell slightly, and things that need to be chewed are more difficult to eat. If you recover well, you can eat normally in three or four days, and then you will get used to it.
I just finished wearing a tongue nail for about a week, because my tongue is a little swollen, so I speak a little Lickitung. Hehe, it doesn't matter if it goes down.
Generally, when you just wear a tongue nail, you will use a longer nail, because considering that your tongue will swell, short nails will feel uncomfortable. When the tongue nail is almost recovered, you can change it to a shorter one, otherwise the long nails will always feel uncomfortable against the maxilla.
Personally, wearing a tongue nail is much less painful than wearing a umbilical nail. It hurts to wear umbilical nail, and the tongue nail seems to be worn out without feeling. :)
