☀️The heat is back, with highs near 90. Sunset is at 8:11 p.m.

When the Red Sox welcome the LA Dodgers for a three-game series tomorrow, the concession stand workers who usually keep the park’s food and beverage operations running might not be there, GBH’s Esteban Bustillos reports. Employees with the union UNITE HERE Local 26, who have been working without a contract since last year, are getting ready to strike. They’re asking their employer — food service giant Aramark — for job protections against automations and for higher pay, noting that other Aramark workers make more. Aramark officials said they will keep the park’s food and drink-selling operations running without their regular workers; the union asked Red Sox and Dodgers fans to support workers by not buying anything at Fenway during the strike.

It may come down to the bottom of the ninth, so to speak: if union members and Aramark management reach an agreement by Friday at noon, they’ll avert the strike, and workers will be at their posts with time to spare before first pitch.

Four Things to Know

1. Two Market Basket executives fired this week, Joe Schmidt and Tom Gordon, said it’s a moment of déjà vu: both were also fired during the Demoulas family struggle for control over Market Basket in 2014 and later brought back to their jobs. The company’s board said Schmidt and Gordon were fired due to “insubordination, making false and derogatory remarks about the company and people associated with it, and inappropriate communications with colleagues.”

“I’m proud of being hired for the right thing, which is the culture of the company — Mr. Demoulas, his family — protecting the communities,” Schmidt told GBH’s Boston Public Radio yesterday. “It’s something worth getting fired for. I’ll be ok.” Arthur T. Demoulas, the company’s CEO who was placed on leave by the board in May, issued a statement calling their dismissal part of a “pre-planned coup.”

2. The State Department is looking into whether to remove Harvard from the Exchange Visitor Program, which lets universities request American visas for students and researchers. This move is separate from the Department of Homeland Security’s attempt to strip Harvard’s ability to request visas for international students or bar people coming to work or study at Harvard from entering the country.

University spokesperson Jason Newton said the university is already complying with the program’s rules and called the investigation “another retaliatory step” from the Trump administration.

3. Worcester City Councilor Etel Haxhiaj pleaded not guilty to charges of assaulting a police officer and interfering with law enforcement during a federal immigration raid on Eureka Street in May. She’s due back in court in September, when she will ask a judge to dismiss the charges. You can see police body camera video of the incident embedded here. 

The woman immigration officers detained that day, Rosane Ferreira De Oliveira, is still in Immigration and Customs Enforcement custody in New Hampshire, according to the ICE detention database.

4. Boston Mayor Michelle Wu is asking the trash and recycling pickup company Republic Services, whose sanitation workers are on strike in the Boston area, to start paying for fines their business customers are getting for overflowing dumpsters, GBH’s Saraya Wintersmith reports.

The company will be on the hook for any fines issued since July 7, as well as fines directly to Republic Services for uncollected trash, Wu wrote in a letter to Republic Services’ president, Vander Ark.

Stress levels are leading to an increase in broken teeth, Mass. dentists report

GBH reporter Craig LeMoult cracked two molars and stumbled across a story that’s more common than he thought: dentists in Massachusetts, including his, have been seeing an increase in people coming in with problems related to teeth grinding or jaw clenching.

There is research that shows a correlation between teeth grinding and jaw clenching (also known as bruxism) and stress. And of 140 Massachusetts dentists who responded to a Massachusetts Dental Society survey in the last month, 75% said they’ve seen more patients coming in for bruxism. 

Craig’s own dentist, Dr. Lina Al-Aswad, who practices in Somerville, said she’s seeing more patients come in for the issue than she did in the first years of the COVID pandemic.

“The thing is, it takes some time,” Al-Aswad said. “People have been stressed for a couple of years and they’ve been grinding their teeth, and now the outcome of that is fractured teeth.”

Clenching your teeth can also make your jaw muscles stronger over time, which means your teeth end up under even more pressure every time you grind them, Dr. Gabriella Lagreca, a prosthodontist who teaches at the Tufts University School of Dental Medicine, told Craig.

So what can you do if you’ve been grinding your teeth? If you’re feeling pain or new sensitivity to cold in your teeth, see a dentist. Cold sensitivity can be a sign that your tooth has fractured, exposing a nerve, which could require dental work.

Your dentist can also talk you through the best prevention options for you. There are store-bought mouth guards, custom guards made to fit your mouth, and neuromodular injections (you might know them by the brand name Botox) to help relax muscles in your jaw.

Craig ended up with two crowns on his molars, and a mouthguard.

“I’m happy to report the mouthguard is working,” Craig wrote. “I think I’m going to pass on the Botox injections.”
