He has told Toon teenager Longstaff he will now be recognised “all over the world" after he netted the winner on his top-flight bow against Manchester United.
Dummett, 28, said: “I was reminiscing with Matty after the game about how good it felt for me when I scored against Liverpool. I was 22 at the time, came on as a sub and we drew.
“But he's 19, he started, we won 1-0, he scored the winner and got man of the match — it couldn't have been any better.
“Matty said to me, 'I won't be able to walk around Whitley Bay now without being noticed!'
“A lot of fans might have heard his name before but you don't always know the face with the name.
“But after that goal, a lot of people all over the world would recognise him now. That was probably the biggest change for me.
“When you go shopping, walking down the street, people say your name.
“You can hear them speaking. If you want to go somewhere quiet, then it can be a bit of a nightmare.
“But I'll always stop and have a conversation or a photo.
“My mates probably get jealous of that, so you have got to appreciate what you've got."
