Using a straw after inlay/onlay: the short version
You can use a straw after an inlay or onlay once the numbness has gone. The restoration is a solid piece of porcelain, gold, or composite cemented into a back tooth, and suction does not affect it. No wound is involved. If you are between appointments with a temporary filling in the prepared tooth, a straw is still fine for drinking; just keep from biting on it over that tooth.
What is actually going on
An inlay fits within the cusps of a molar or premolar, and an onlay extends over one or more cusps. Lab-made versions take two visits: the tooth is prepared and covered with a temporary, then the finished piece is bonded in with resin cement, usually light-cured so it is firm when you leave and reaching full strength over about a day. Same-day milled versions skip the temporary. Liquid moving past the tooth has no effect at either stage. A temporary is softer and can be pulled out by sticky food or cracked by hard bites, not by drinking. With the final piece in, the tooth may be sensitive to cold for a few weeks, because bonding deep in a back tooth irritates the nerve a little. Sending cold drinks down the other side with a straw is an easy fix.
The first time, step by step
An inlay or onlay puts no limit on straws beyond the numbness. These go on back teeth, and for a lower one the block often numbs the lip, chin and half the tongue for a few hours. When all of that has woken up, drink water first and send it down the other side. Then close your teeth slowly. With the anesthetic gone you can finally judge the bite, and a restoration that meets first, or a temporary that feels proud, should be reported to your dentist. After the first visit, remember there is only a temporary in the tooth.

Wait time
After a inlay/onlay, you can resume using a straw when numbness wears off.
Why
No concerns
Tips for Using a straw After Inlay/Onlay
- 01Aim the straw at the opposite side if the restored tooth reacts to cold; back teeth are easy to bypass that way.
- 02With a temporary in place, avoid clamping a firm straw between your back teeth on that side.
- 03Hold off chewing gum and toffee-like sweets until the permanent piece is cemented.
- 04Let your dentist know if the tooth feels high when you close, or if floss shreds at the edge of the new restoration.
Common mistakes
- 01Drinking something hot through a straw on the way home after a lower block. The stream lands on a tongue that cannot feel, and the burn only announces itself hours later when sensation returns.
- 02Chewing the ice at the bottom of the cup on a newly bonded onlay the same day. The resin cement is still gaining strength over roughly the first day, and hard crunching is a poor first test of it.
- 03Ordering a drink with caramel drizzle or chewy toppings while a temporary is in the tooth. The straw is harmless, but sticky pieces can grip the temporary and lift it out between appointments.
