Chrissy Teigen is being mom-shamed again – this time over Luna's first trip to the dentist

Another day, another clap back from Chrissy Teigen.

The cookbook author and "Lip Sync Battle" host shared an Instagram video of daughter Luna, 3, enjoying her first trip to the dentist's office Tuesday. 

"So proud of my toons at her first dentist appointment!" Teigen captioned the video of Luna brushing a stuffed animal's teeth while sitting on grandma Vilailuck Teigen's lap.

Like clockwork, sanctimonious trolls chimed in, questioning why Teigen didn't take Luna to the dentist sooner. "What age do they start over there? My daughter started seeing a dentist at a (year) old," one commenter wrote. 

Another chimed in, saying, "I’ve always heard at least by age 1 or within 6 months after the first tooth erupts. Luna definitely should have seen a dentist multiple times by now as kids should go twice a year!"

The mother of two is no stranger to criticism when it comes to her parenting style. In fact, she is all too familiar with being mommy-shamed, as evidenced by her reply.

"Was waiting for this," Teigen wrote. "U guys never fail me." 

(FWIW, Chrissy, the American Academy of Pediatric Dentistry says: "In order to prevent dental problems, your child should see a pediatric dentist when the first tooth appears, or no later than his/her first birthday." Sorry.)

Chrissy Teigen, Luna Simone Stephens and John Legend attend John Legend's launch of his new rose wine brand, LVE, during an intimate Airbnb Concert on June 21, 2018 in Beverly Hills, California.

Teigen is a legend in the clap back game, most recently setting straight a troll who criticized Luna's hair.

It happened earlier this month when the model posted a couple of adorable Instagram videos of her and John Legend's daughter showing off her impressive negotiation skills in "Candy Court."

But someone was more concerned with Luna's appearance than her bargaining. "Finally someone Brushed her Hair," the user wrote, adding a couple laughing/crying emojis.

Teigen, who is also mother to 1-year-old son Miles, fired back: "All by herself! maybe she can come do your make up."

Ouch! Maybe trolls will learn not to mess with Teigen and her brood one day.
