This hard-fought win takes Real Madrid six points above fifth-placed Sevilla - which is probably the main issue really.
They're still 17 points behind leaders Barcelona and 10 behind second-placed Atletico Madrid.
However they could move up to third if they win their game in hand - at Leganes on Wednesday.
Cristiano Ronaldo has scored eight goals in La Liga since the start of 2018, more than any other player.
Karim Benzema had not scored in the league since November.
Here's what Spanish football writer Andy West has to say...
Yet dull 0-0s in the Premier League seem to drag on for years.
The kind of game you never want to finish is sadly over now.
Sergio Leon denied a ninth goal of this game by a sliding tackle. And the corner is cleared.
It's all over now.
If ever a striker has needed a goal. Karim Benzema scores only his third La Liga goal of the season. Cristiano Tello gifts the ball to Benzema. The striker finds Lucas Vazquez and then gets in the box to slam the winger's cross home from near the penalty spot.
Three minutes added on. If only there could be 90.
Karim Benzema loses the ball with his first touch. That'l go down well in Madrid.
Don't see this one too often as Real Madrid defend a one-goal lead - Cristiano Ronaldo is replaced by Karim Benzema. Plenty of whistles from the Seville crowd.
Free-kick to Betis as Dani Carvajal commits a foul on Cristian Tello. Joaquin went close from this range earlier. They try to take this one short for some reason, but the referee wasn't ready so they get another chance.
Joaquin's effort this time is nowhere near as good and it's well over the bar.
Never write off Real Madrid (conceding).
Junior crosses from the left and substitute Sergio Leon pulls one back at the back post with almost his first touch.
Five minutes left for an equaliser.
Getting fouled was Andres Guardado's last action - he's replaced by striker Sergio Leon. Former Barcelona winger Cristian Tello is also on for Ryad Boudebouz
Eighth yellow card of the game as Real Madrid midfielder Casemiro catches Andres Guardado.
Ten minutes to go, I think Real Betis' optimism has dipped now. Not sure they're showing the same level of belief as they were.
When I asked earlier if this was the worst title defence by an elite team, I had forgotten about only two seasons ago!
Iain S Wilson: How about the abomination that was Chelsea the season Leicester City won the Premier League - 31 points off by the end of the season. Real Madrid could still end up a lot closer, just need a bit of confidence
Real Betis bring off Swansea loanee Jordi Amat and bring on former Real Madrid and Manchester City midfielder Javi Garcia.
That's Gareth Bale's night over as he's replaced by Isco for the final 17 minutes. He hasn't done badly but he's not exactly made an impact like Marco Asensio has with his start.
